Downloaded Pretty Little Liars on my Apple TV app on iPad Pro have suddenly disappeared

Hey everyone,

I've recently bought iPad Pro, and it works perfectly. The only issue that I've faced (which might sound strange to everyone) is that for instance, when I try to download like 5 episodes of Pretty Little Liars series that I've purchased about two years ago (US iTunes) after five days of just downloading them, they suddenly disappear, as if I'd never downloaded any episodes from this series and it only happens to the downloaded Pretty Little Liars episodes. This has happened to me twice, last time I'd downloaded 80 episodes and just after four days I've noticed that all of the downloaded episodes have been removed and it is really strange. Obviously, I can stream them or redownload them but the same thing would happen if I try to download them. What's odd is that I don't have any space issues (since 1.2 TB is available) and I'm using the most recent iPadOS 15.3.1. Does anyone know what might cause this? I genuinely appreciate your consideration.
