Play Again Button Bug

I was playing some 5v5 norms trying to practice midlane (I main support and want to branch off). So after a game of playimg support I hit play again thinking I could try and get mid nexy game -which I didand everyyhimg was dandy until the game ends and it turns out thr gamemode was ranked. Of cpurse I'm upsey becauss I lost but whatever because now I am not going to ever trust the play again button.
