Bug with low pri queue

Hi guys im new and today i found this weird bug. I had low pri queue for 20 mins which i know i deserve but whie i was waiting and there was 2 mins left, i accidently double clicked and the setting button which you normally cant press in low pri queue. When i clicked it, i was out of the queue and was suddenly on the regular queue. The queue timer said 18 mins and 20 seconds. Sorry for the bad language, im not good at englis
