AppleTV doesn't show all purchased movies

Hi,

My AppleTV 4K doesn't show all movies I bought. I'm not talking about the recently bought section, but the Movies section, that shows all movies.

If I want to see a movie I own, and search for it, it offers to buy it again, which of course I won't do.

Funny thing is that on my mac, I have them in my TV application and can play them there... BUT all the movies not showing up on my Apple TV 4k all have missing artworks in the macOS TV application.

TV on my Mac shows them as "ghosts". They are downloaded, they are on my hard disk, I can play them on my Mac. But they don't have the artwork shown.

This is exactly the movies that are not showing up on the AppleTV 4K hardware.

Any idea? I turned off and on Media Sharing on my Mac but this didn't change anything.

Thanks for any help.
