Adding WSDL to project creates only types, no entry to app.config and throws three errors

Question

I'm trying to add service reference to my (.NET 4.6) project.
When I choose Add Service Reference and add URL of WSDL I can see it is correctly discovered:

I've unchecked Reuse types in all referenced assemblies as shown below:

But when I click OK I get three warnings in Error List window:

Warning 1 Custom tool warning: Cannot import wsdl:portType Detail: An exception was thrown while running a WSDL import extension: System.ServiceModel.Description.XmlSerializerMessageContractImporter Error: Unable to cast object of type 'System.Xml.Serialization.StructMapping' to type 'System.Xml.Serialization.MembersMapping'. XPath to Error Source: //wsdl:definitions[@targetNamespace='http://bik.pl/cc/big']/wsdl:portType[@name='BIG']

Warning 3 Custom tool warning: Cannot import wsdl:port Detail: There was an error importing a wsdl:binding that the wsdl:port is dependent on. XPath to wsdl:binding: //wsdl:definitions[@targetNamespace='http://bik.pl/cc/big']/wsdl:binding[@name='BIGBinding'] XPath to Error Source: //wsdl:definitions[@targetNamespace='http://bik.pl/cc/big']/wsdl:service[@name='BIG']/wsdl:port[@name='BIG']

Warning 2 Custom tool warning: Cannot import wsdl:binding Detail: There was an error importing a wsdl:portType that the wsdl:binding is dependent on. XPath to wsdl:portType: //wsdl:definitions[@targetNamespace='http://bik.pl/cc/big']/wsdl:portType[@name='BIG'] XPath to Error Source: //wsdl:definitions[@targetNamespace='http://bik.pl/cc/big']/wsdl:binding[@name='BIGBinding']

I've tried different options while importing, but I get those errors all the time.
I've validated WSDL using www.wsdl-analyzer.com but it shows no error:

Here is quality report: https://www.wsdl-analyzer.com/qualityReport/show/1784995829?version=1

SoapUI correctly shows all operations and I'm able to do them from SoapUI, but I need to add reference to my project in Visual Studio.

Below are links to WSDL and XSD:

https://wasstt.infomonitor.pl/39D97477-0709-455f-A7C8-6498B600AC5A/ws/BIG/WEB-INF/wsdl/dluznik.wsdl

https://wasstt.infomonitor.pl/39D97477-0709-455f-A7C8-6498B600AC5A/ws/BIG/WEB-INF/wsdl/dluznik.xsd

How can I import this WSDL into my project? I'm unable to modify structure of that WSDL, so I must use it as it is.

EDIT: I've installed XMLSpy and opened that WSDL in it. After opening I got message saying that WSDL is valid.

Probably the problem has already been solved in a different way (other technology, resignation from the contract), but if you are still interested, the problem is that wsdl.exe don't support circular reference in element definition.

<xs:element name="raport-z-rej-zap">
    <xs:complexType>
    <!-- ... -->
        <xs:element ref="tns:raport-z-rej-zap" minOccurs="0" maxOccurs="unbounded" />
    <!-- ... -->
    </xs:complexType>
</xs:element>

All You need is to define named complex type insted of anonymous:

<xs:element name="raport-z-rej-zap" type="tns:Raport-z-rej-zap">
    <xs:annotation>
        <xs:documentation>Struktura raportow z Rejestru Zapytan (ref. 6.6)</xs:documentation>
    </xs:annotation>
</xs:element>
<xs:complexType name="Raport-z-rej-zap">
    <xs:choice>
        <xs:sequence>
            <xs:element name="naglowek" type="tns:TypNaglowekRaportu" />
            <xs:element name="pytajacy" type="tns:TypDanePodmiotuPytajacego" minOccurs="0" />
            <xs:element name="dane-zap" type="tns:TypDaneZapytaniaZRejZap" minOccurs="0" />
            <xs:element name="uwagi-i-ostrz" type="tns:TypUwagOstrzezen" minOccurs="0" />
            <xs:element name="podmiot" minOccurs="0" maxOccurs="unbounded">
                <xs:complexType>
                    <xs:sequence>
                        <xs:element name="dane-podm" type="tns:TypDanePodmiotu" />
                        <xs:element name="tresc-rap" minOccurs="0" maxOccurs="unbounded">
                            <xs:annotation>
                                <xs:documentation>Tresc uprzednio przekazanego raportu</xs:documentation>
                            </xs:annotation>
                            <xs:complexType>
                                <xs:choice>
                                    <xs:element ref="tns:raport-fin" minOccurs="0" maxOccurs="unbounded" />
                                    <xs:element ref="tns:raport-dok" minOccurs="0" maxOccurs="unbounded" />
                                    <xs:element name="raport-z-rej-zap" type="tns:Raport-z-rej-zap" minOccurs="0" maxOccurs="unbounded" />
                                </xs:choice>
                            </xs:complexType>
                        </xs:element>
                    </xs:sequence>
                </xs:complexType>
            </xs:element>
            <xs:element name="suma-kontr" type="tns:TypSumaKontrolna" minOccurs="0" />
        </xs:sequence>
        <xs:element name="blad-przetw" type="tns:TypBladPrzetw" />
        <xs:element name="blad-struktury" type="tns:TypKomunikatAdministracyjny">
            <xs:annotation>
                <xs:documentation>zadanie operacji na bazie danych odrzucone z powodu bledow struktury (rezultat = blad struktury).</xs:documentation>
            </xs:annotation>
        </xs:element>
        <xs:element name="certyfikat" type="tns:TypRaportCertyfikat" />
    </xs:choice>
</xs:complexType>

Or delete from wsdl element:

<wsdl:operation name="pobranie-raportu-z-rej-zap">

AFAIK You can't call this operation - it is reserved for BIG Infomonitor use.
