Liked videos disappearing. Why?

It started three days ago. I like a video on my fyp, scroll back, and the video isn't liked anymore. When i go to liked videos on my profile, it isn't there and the latest video i liked is 3 days ago. And it's on likes only, i can repost or favorite normally. Has anyone else experienced this lately? I tried clearing the cache, force stopped the app, restarting the phone but nothing works. If you know how to fix that, please tell me.

Thanks in advance 🙏.
