You probably went through the wrong entrance. Like if you have to go through Temple of Crota to get there you won't be able to do it correctly.

That may be part of it. I started up the mission and then went and grabbed 2 golden chests I forgot to grab earlier. Then I went back to the correct entrance. But, as LEMONS said I had to go back to the Hall and then reenter the shrine.
