Missions are bugged

Yo so im playing a League match and i got a new mission (MSI) so it says either win a game with premades or win 3 games. I won 5 games and only 1 game is "recognized" by the mission. I played an additional 2 games (victories of course) still nothing. Rito fix your fucking game man. You only got 1 and its becoming worse and worse!
