Collections not working

Hi, so, ive been having a problem for about two months now. My videos are all saved when I favorite them, however, some of my collection folders refuse to load. And those folders don't even have a lot of saves, some had been working before. One of my heaviest ones has 480 saves and was working just fine, today it started glitching again.

When I tried to solve it by deleting the other favs in the publications and folders, the folders showed as all cleared, but the number continue from 10-50, as if there were still videos saved. But there are no videos and it says its cleared.

And, I never save things outside of my collections. I like everything organized. I did the math on all my collections, and I have about 3k videos saved. But tiktok shows in publications that I have 11k?? I'm very confused. This account isn't very old, and I don't favorite videos outside of the proper folder. I also tried cleaning cache, forced the app to stop and took down my other account, just in case it had been a bug because of it.

Did anyone go through anything similar?
