[BUG THREAD] The Sims 4 CAS Demo

I seem to be having a problem with sims I've saved to my library duplicating and bugging out at the top of the library screen.  All of the duplicated sims say they have been created by me, even though lots of them were downloads from the gallery.  Sometimes the family picture loads, sometimes it is just a blue box.

When I click on them, no family pictures appear, only a blue flickering screen with empty/partial trait boxes.  There are over 40 of them in my library, and they are duplicates of sims I actually have in my library.

I can't open any of the offending families and actually look at them in CAS, and so I went through and tried to delete them all, but they just reappeared when I opened my library back up.

Any easy way to fix this? It is starting to get on my nerves ☹️

Here are screenshots of what I am talking about.

This is what the top of my library looks like, every single family you can see is a bugged out duplicate:
