Problem with achievements – Juggle It Review

This is a really fun game but after I achieve certain achievements, the achievements list says I've achieved it but when I close the list and open it again later, it says that I have not achieved it. After It said how i played 9 games, I closed the list and opened it again to see how it said I only played 5 games. I am not sure if this is a problem with the game or Game Center. Fix this bug and I will change my rating to five stars.
