Leaver Buster Reset after last game

Left game for personal reasons. Got 5 low priority games with 20 min waiting time. So far so good, played 5 games with low priority queue and the 20 min waiting time.

After the 4th game the "1 games left with low prio" appeared so I started the last game ... waited 20 min ... got into game ... finished it ...

"5 games left with low prio"

in the last 5 games I didn't left nor went afk ...
