I have this issue a lot whenever I try to watch shorts on desktop with it loading the wrong info for the short with the video, usually the mixup is the video of the next short coming up with the info for the current one.
Same thing can happen in the mobile app if you leave the app while on a short and come back, it'll load just the video for the next one without changing anything else.
