Can't accept match.

I currently have, 5, 20 minute lower priority queues left. Which is fine, I can't play the game, I need to take the punishment. But what isn't fine is how I've sat through 2 of them and yet they are not gone. This is because, The first time, The match accept button came up and I clicked it fine. But then, someone else didn't and a match was found immediately after but I couldn't accept because the old match accept was still there. So once the second one's time runs out, I get sent back to the lobby without it removing my lower priority queue and me having to sit through another.

THEN the second time I get into 3 different matchs fine accept someone leaves in champ select. After the third time, a match is found immediately after and the same glitch happens.

So to get rid of one cooldown I had to sit through 60 minutes of lower priority queue. ( And maybe more if it happens again.)

I'm using the newer client and this hasn't ever happened before today.
