Multi-Player Mode Atziri Temple Issues

When I play multiplayer with a friend, sometimes the medallions show on the mini-map but we cannot see them to activate them. Since we cannot activate the medallions we lose out of some of the rooms and treasures you can get when completing the room. We attempted to leave and return or change party leader with no results. Logging out and back in after disbanding party will still not fix the issue, we have to close the run and lose the points.
