Possibility of Frontline queues getting glitched

So freelance queues were at a 15min avg wait time on Crystal during the afternoon. I queued as a freelancer and my friend did too 2 minutes prior to me. His queue popped at 19min and it was a fresh game. While mine was at 17min and I did not get into his game. So somehow the duty finder waited 17min+ to find players and it did not include me, a freelancer.

I find this weird because the 72nd player that loads up duty finder would've triggered the game to pop immediately and everyone who queued up before that 72nd player would have got into a game. The only exception is if you queued for one specific GC and they do not have any spots left. But I turned freelance on and I still couldn't get into the game despite waiting 17min and my friend did at 19min. I believe what happened was that the Frontline Roulette algorithm got glitched and is the cause of the long queue times.

Does anyone else think the frontline queue is glitched or is this normal?
