Door In Desolations Edge won't open

I’m on the quest “Footsteps of Giants,” and before you enter Tazandeer Ruins, there is a door you have to open by killing all the Guardians in the area. The door won’t open because the last Guradians I need to kill, spawn behind the closed door and now I am stuck here. I’ve tried saving and quitting, even closing the application but even after those, the Guardians still spawn behind the closed door

Update: I killed the Guardians on the other side by throwing a bunch of Storm Fronts however, the door still hasnt opened
