Games only stay hidden while I'm looking at my library. If I close GOG galaxy and reopen it, the games are no longer hidden.

EDIT: the games also un-hide themselves when I try to do literally anything in GOG galaxy. I tried googling the issue, but to my konwledge, no one else has posted about this bug. Am I the only one experiencing this?

EDIT 2: Ok, so it turns out that restarting my PC is the only way to refresh my library. I have to fully restart my PC every time I want to hide or unhide a game.
