I can see several lightning/fischer games, but there are games that are created that pop-up in the top right of my screen.  I can click the pop-up, see the game in one window, go to another window in the Join Games window, and it won't be there, though it will be active for joining.  I can join and leave the game in question if I caught it from the pop-up window, but it's not in the Join Games list (which is not filtering out lightning or fischer).

Game link below (I can still join this game at time of posting, but it is not in the "join games" list of games.
