Couldn't ban in Beta client

I was just forced to dodge a ranked flex game because I couldn't ban. None of the champions were showing up for me to show who i wanted to pick. None of the bans made by my team or the enemy team showed up (I heard them, tho). And I was unable to ban because no champs showed up for me to select. I lost 5 lp for being forced to dodge =( I'm using the legacy client for now. I don't want that happening to me again. so lame =(
