MultiautoCompleteTextView ime keyabord does not show suggestions

Question

I'm using MultiautoCompleteTextView. it works perfect. strange problem though that some devices do not show keyboard suggestions:

Using Nexus 5

Using galaxy s6

Some Code

<MultiAutoCompleteTextView
    android:id="@+id/fragment_write_text_editText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="@dimen/text_editor_margin_top"
    android:gravity="start|top"
    android:hint="@string/enter_text"
    android:imeOptions="normal"
    android:inputType="textCapSentences|textMultiLine|textAutoComplete"
    android:maxLength="1200"
    android:backgroundTint="@color/primary"
    android:textSize="16sp"/>

public void setupEditorBox (View view) {
    mEditTextBox = (MultiAutoCompleteTextView) view.findViewById(R.id.fragment_write_text_editText);
    mEditTextBox.setThreshold(1);
    mEditTextBox.setTokenizer(new HashTagTokenizer());
    mEditTextBox.setAdapter(new HashTagAutocompleteAdapter(getActivity(), R.layout.auto_complete_tag_item));
    mEditTextBox.setOnItemClickListener(this);
}

In Nexus Devices you can fix it setting the InputType.

mEditTextBox.setInputType(InputType.TYPE_CLASS_TEXT);

At least with a simple ArrayAdapter and the MultiAutoCompleteTextView.CommaTokenizer, setting the InputType fix this issue.
