Dungeon Finder is bugged in 5-man premade groups, only showing 4 players when 5 have queued

Does anyone else have this bug when playing in a 5-man premade group? When queued for random dungeons in TWW Timewalking for example, the actual queue only shows 4 players instead of 5. Always 1 DPS is missing, even though the group has all needed roles.

was just about to post this. it happens to me EVERY time we try it. usually this results in a few people quitting (especially if one is a high damage/tank) so it slows your queue time down a ton :\

only been happening about maybe 2 weeks though i think
