Stuck in Lobby

Queued up for game, entered said queue with no problem, entered champ select fine, entered game fine, game ended due to remake, left game fine, entered new lobby fine. This is where problems started to occur. Started to queue up for new game. Queue ran longer than I thought was necessary, so I tried to drop queue to restart the timer. Could not leave queue. Hitting the X button in the lobby did not exit queue, nor did hitting the X button in the small box in the friends tab whilst in the home panel. Relogged. Logging in brought me to the same lobby I was in, except now no matter what position I chose, including primary pick fill, I am told my team needs to cover more positions before queuing(Image linked). Pressing the X brings me to the home screen, but the play button is replaced with a lobby button that brings me back to the same lobby (it never having been closed down). Relogged. Same thing. Repaired client. Stuck in same lobby. I'd rather not reinstall the game completely, but That's where I am at this point.

UPDATE: I've reinstalled the game entirely. The game is currently updating to the current patch. Will update once it finishes.

UPDATE II: After re-installing and re-updating, the issue seems to have been resolved. For now. I will now try to play a game and see if the issue happens again.
