So it just seems like you did get added to the queue, but the matchmaker just found 2 other people to start the match then. I will go through and see if there are any issues, but remember, there can be cases where even if you are first in line, someone else can get put into a match before you.
When you log out, it does kick you out of the queue. I guess the menu keeps its previous state and says you are still in queue when you relog. I’ll make a fix to make sure the menu shows you queue status properly when you relog.
