Created attachment 112862 [details] shot of the screen with 0 a.d. listed as game For some games the category labels are in the app delegate is empty. e.g. when going into the global apps list "0 A.D." is listed as a Game, when then going into the Game list it has no category label anymore. From looking at a bunch of affected apps I'd say that the categories aren't mapped into the UI. e.g. 0 A.D. is StrategyGame but there is no category like that showing up in the list in discover. I am attaching a bunch of appstreamcli dumps of examples I could find of this happening.
