Apple TV purchased movies missing

Recently, all my purchased movies disappeared from Apple TV. Now, if I want to watch one of them I have to go through the process of purchasing it again and then it says I already have it do I want to download it and then sometimes I can watch it and sometimes I cannot. Does anybody have this problem? Are using a 4K TV on the latest software. None of my movies except for the last nine show up on any of my other devices either
