Campaign Commendation Bug?

So after a couple of frustrating hours, I completed the mission ‘Forerunner’ on legendary while on my quest to achieve the Mark VI helmet and now when I go into my profile with my campaign stats it reads that I haven’t competed it…? Do I have to restart the mission or wait for 343 to fix up their -Yoink-?

Cheers

Same thing happened to me on Requiem and Forerunners. Absolutely do not want to run through Requiem again on legendary. I would think this is fixable without us having to go through those levels again, but I don’t know.
