Sync issues.

I'm noticing a lot of issue with the Sync for my account. Examples would be say Baldur's Gate Enhanced Edition which does not show on my list here no matter how often I sync. It shows as owned on Steam. It is picked as owned by steamdb, but not here. I've got quite a few like that. Makes it annoying when those items are on the list of possible GAs to enter even when filtred for owned games.

Is there a reason some games aren't picked up right and is there anything I can do to help it? It is not like I haven't synched since the summer sale.
