Warning: URL namespace 'invitations' isn't unique

[hellogbg]

Hi,
thank you for good work with this useful plugin.

I am getting this warning when starting django server:
?: (urls.W005) URL namespace 'invitations' isn't unique. You may not be able to reverse all URLs in this namespace

Do I have to remove the following line coming from django-invitations?
path('invitations/', include(('invitations.urls'), namespace='invitations')),
