(urls.W005) URL namespace 'LnkIn' isn't unique.

Question

Hi I'm getting this error when doing my migrations or using the python manage.py runserver command.

(urls.W005) URL namespace 'LnkIn' isn't unique.You may not be able to reverse all URLs in this namespace. 

This is how I have my urls.py inside my app directory (LnkIn).

from django.conf.urls import url
from . import views

app_name = 'LnkdIn'

urlpatterns = [
    url(r'^$', views.index, name='index'),
    url(r'^register/$', views.register, name='register'),
    url(r'^login_user/$', views.login_user, name='login_user'),
    url(r'^logout_user/$', views.logout_user, name='logout_user'),
    url(r'^(?P<user_id>[0-9]+)/$', views.profile, name='profile'),
    url(r'^(?P<song_id>[0-9]+)/favorite/$', views.favorite, name='favorite'),
    url(r'^trabajos/$', views.trabajos, name='trabajos'),
    url(r'^crear_oferta/$', views.crear_oferta, name='crear_oferta'),
    url(r'^(?P<user_id>[0-9]+)/create_trabajo/$', views.create_trabajo, name='create_trabajo'),
    url(r'^(?P<user_id>[0-9]+)/crear_amistad/$', views.crear_amistad, name='crear_amistad'),
    url(r'^(?P<user_id>[0-9]+)/delete_trabajo/(?P<trabajo_id>[0-9]+)/$', views.delete_trabajo, name='delete_trabajo'),
    url(r'^(?P<album_id>[0-9]+)/favorite_album/$', views.favorite_album, name='favorite_album'),
    url(r'^(?P<album_id>[0-9]+)/delete_album/$', views.delete_album, name='delete_album'),
]

And this is how I have my urls.py in my main directory.

from django.conf.urls import include, url
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^LnkdIn/', include('LnkdIn.urls')),
    url(r'^', include('LnkdIn.urls')),
]

if settings.DEBUG:
    urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

I really have no idea what could I've done wrong. I checked in my views and in my templates and everything seems to be fine, I don't seem to be having any typo on my urls. I've search but haven't find this error, I've seem similars one and they suggest to check not having mistakes in the urls.

I'm using Python 2.7 and Django 1.10.

You are importing LnkdIn.urls twice to your application urlpatterns.

You should only do it once, so choose either one from the section below

url(r'^LnkdIn/', include('LnkdIn.urls')),

or

url(r'^', include('LnkdIn.urls')),
