WotLK Dungeon finder and party major glitch

[Welperinho]

Hello guys, so I have been in a party clearing a dungeon "Underbog" and when the dungeon has finished everyone from the party left and I have returned to the main city. After that I have tried to requeue for another dungeon, but it kept saying your party member "The name of the party member" have not selected any roles. After some time of trying it started saying your group members are not online. When I try to invite someone in a party it says "is not in your instance". I have tried /reload , unstuck from the website , relogging and other stuff nothing seems to work any possible help or solution?
