Bugged playtime in games that were favorited before this update

Good evening, I wanted to inform you about a bug in the game time, because I formatted my PC in the last few days (after the last update) and the game time is very buggy in games that were favorited in the account, including not even being able to remove from the library, this is my old account, I created a new one for this bug to stop happening, I hope they solve this problem in relation to favorites, for now I will avoid this functionality until everything is resolved
