It seems like filter settings are lost when you come out of a game:
E.G.:
1 - I set my filter to show only "available games"
2 - Only games with open slots are shown
3 - I enter a game and play it
4 - When I come out *all* games are shown again
5 - My filter settings still show that they are set to show only available games
To fix it I have to cycle the setting a few times back to "available only" and exit, at which point it works ok again
