Go to the Player XP screen. Give all your points to on of the attributes. Press X. Then go back into that attribute again and remove all the points by pressing left on the d-pad not the square button. Then dont press X, instead press O. For example: lets say your created character's forehand is a 30. Press X and give your exp to the forehand. Let's say its a 32 now. Go back into the forehand attribute and remove all the exp you just gave it by pressing left on the d-pad then press O when the level shown is 30 again. It should still be a 32 but you get the exp points back.
