By going to MOHW and then back to BF3 in Battlelog BBLog forgets its settings.
I can understand that as of right now MOHW is not supported however this is a bug that does not require the game. (as stated in the stickied post)
Update:
This only happens Sometimes!
This also seems reversible (Sometimes)
When it isn't reversible you should see MOHW Theme fix itself 100%

The reason is that BBLog on MOH:W is in a totally uncontrolled state, if a bug occurs during a storage process than this could happen.
Next update come tomorrow which totally disable bblog on moh:w.
