So I just built a new PC, and of course I am going through my library again. I had previously hidden some games in my library. I am trying to unhide them.

I went to the filter selected hidden Right clicked on the game I wanted to unhide. It disappeared from unhide but the games beyond it did not move, So I went back to my normal game list and the unhidden game did not show up. When I went back into the hidden games list it was there again.

Anyone know what might be causing my games not to unhide?

These are GOG games some bought some free. Doesn't seem to matter which platform they are on though. Tried unhiding some EPIC and XBOX games also.
