I can't say that this "just broke", but the new sort feature for achievements and controller support, etc... is not working correctly for all games. For instance I went to my library and sorted by achievements or controller support and it left out the Witcher 3 even though it's listed as having achievements and controller support and clearly does. Seems to work though if you sort by achievement's in the game section (the game is listed) but not from my library.
EDIT: It may or may not be specific to the Witcher 3. A quick overlook makes me think it's the only one but can't be sure.
