Doesn't work right – U.S. State Capitals! States & Capital Quiz Game Review

The app works good the first time you set the favorites but when I tried to Change them it worked until you close the app then it sets the favorites back to what they used to be which is really unhelpful. please fix this problem, besides that this is a great app to study states and capitals!
