(Champion Select Bug) Enemy leader was able to ban 4 champions!!!!

I do not know how it happened because my conection lagged and I did not get into the room until after two bans had been made (instead of sending me to the game, the client first send me to the initial screen where you select the play option for a couple of seconds, then sent me into the champion sleect room). But on LAN server the enemy team was able to abn 4 champs
