Unable to call elevator to progress

Zoned in to mission in progress. Found team discussing how they couldn’t go further and noted the elevator is on the wrong floor and unable to call it to move. There was no button to press.

Was a Uprising difficulty, don’t recall mission name since they are so similar. Hopefully the screen shot helps out folks who are more familiar.

My team finished the event and the elevator never came down. We had to quit out. It has only happened once.
