I have tried everything I can think of to get this to complete. I am using the Arc Subclass and nothing else while doing The Devils Lair Strike. I have abandoned and required the quest. I have restarted the game. I even went to Cosmodrome and launched the strike from there. I have run it solo and with a fireteam and nothing is getting the completion done for this quest. Please advise on any other tricks or steps I can do to fix this.
