{Can not select a champian when I finished my level 7 game}

After I played a game with my friend,** I level up to 7**, so I can choose an champ between one of three. The problem is the area that shows the Buttons are at the middle. When I move up and trying to press them, they dissapair**(the view ablilities and select)** , so there is no way I can Pick a champ and keep going on! I think it is because the Judgment area of this page buged. I hope this got fix and I can play my games on this account.
