TikTok Videos I liked keep disappearing

Hello everyone, I’m not sure if it’s just me, but I’ve been experiencing a really strange TikTok issue. After a certain amount of time (around 2–3 months), the videos I’ve liked start to lose their red heart (❤️). Even videos I was 100% sure I had liked before suddenly show up as if I never liked them. The same thing happens with videos I favorited before and now show up as if I never liked them. Again, I’m pretty sure I liked them before.

It’s super frustrating. Is anyone else dealing with this, or is this some kind of TikTok feature to prevent “over-liking”?
