because matsuri matching system is pretty broken, because doesn't matter at all your queue if another queue is in action at the same time. Who comes first first served there, sadly.

Lets say a level 85 is in queue and lost the previous battle or has still to do his 1st battle or is waiting since more than 60 seconds, if you click on 'match' at that point you will be matched with him because is 'his' queue that get priority over yours.
