Issue with opening the map in Sunken Temple of Qarn

Hi guys, mb someone can help me with my problem
yesterday i went in dungeon called "Sunken Temple of Qarn". Main reason i went there is to get achievment "mapping the realm : Sunken Temple of Qarn". But map doesnt open near the end of the dungeon. I try to go in dungeon several times, with different squad's, i though it may be some kind of glitch! But looks like it's not! Map won't open anyway =( I try to stay in the middle of the zone, or on top, still dosnt opened. And most strange that party member, who have PS3 version open the map succesfuly!
Help pls
Here some screenshots for you to better understand my problem :)
