Champ Select Bug

So I started noticing it the other day that when you hover over a champion in champ select in the new client, it can sometimes auto lock in a different random champion. I don't see why. Like just now, I had selected Riven for top lane in ranked. I click "LOCK IN" and all of a sudden I get question marks in the chat from my team only to see that it made me lock in Ashe. Not too sure what is going on? But it's happening often and making me dodge a lot.
