Saved videos won't show up in favourites

For like a day or two now I've been having this problem where any video I try to save to my favourites, just doesn't show up in the folder???? I still have my saved videos as favourited, but any new videos I try to save just won't show up in my favourites and I don't know why.

I've cleared up tiktok cache but still nothing, I've redownloaded tiktok just to see if that might work, and even restarted my phone but still nothing worked

I even asked some of my friends who have tiktok, if they have the same problem but they said no, so I'm assuming it's just me.

If anyone knows what's going on, please tell me. This is getting on my nerves smh.
