⚠️ warning next to games I own and can play

[Daeth Vader]

So I have randomly been getting the triangle with a exclamation mark in the middle of it which normally means it’s a game you down own/don’t have the disc inserted for, but these games still allow me to play them and say I own them, but for my friend who i’m game sharing with it says he can’t download/play them unless he purchases them (these games were working a week ago btw) Does anyone know how to fix this?
