Game Center High Score Problems

Yesterday i was playing Flappy Bird with my iPad 2 with iOS7, i was connected to wifi and i made 264 points in flappy bird and i was in the second place in my friends list and today i open the game start playing and I open gamecenter to see my friends scores and my 264 high score now is 97 I don't know what happened but my real high score now is 97 and i can't change it to the real one, I don't know why did this happened but it's really annoying that i can't see my real high score and that i need to start all over again I hope that this gets fixed as soon as posible. If anyone is having the same problem or knows how to fix it please let me know.
