Im getting random fortnite videos glitching into my for you page?? (Clip below)

It started this week. I'll be watching a tiktok that has nothing to do with fortnite and if I touch the screen, fortnite appears. The first time it happened I thought nothing of it. But it has continued to happen at least five times now. It only happens on my fyp. If I go to the creator's profile and look at the tiktok, it does not have fortnite in it. Why is this happening? Im being hacked??? Here is a clip of it happening. I've searched it but I think im the only one.
