Unlock one card on each of the 30 MLB teams

I have at least 1 Card from each 30 MLB Teams and this Achievement will not unlock. I had this happen before when going for the "Teamwork" Achievement, but it unlocked after I completed a game, but it is not working this time...

EDIT: I see this has been posted before. Sorry, but has anyone discovered a fix?

ok guys had the same problem, make sure u look at the cards becasue some cards are "freebies" and they dont count since u didnt unlock them
