[Python] PyCharm Not Properly Recognizing Requirements - Python, Django

Often requirements show up in requirements.txt like this:

But in INSTALLED_APPS it appears as registration. So when you import like:

from registration.signals import user_registered


This is valid but PyCharm is showing a red squiggly line under the word registration in from registration... that says "Package 'registration' is not listed in project requirements".
