Service Record issue regarding Campaign.

I have completed Requiem on Legendary Difficulty and it says so in my Service Record but when I go to my commendations for the 117 armor it says that I have not received credit for it. Any fixes? suggestions?

If you mean the Master Chief Armor then you have to play the whole campain on legedary.

I know that. But requiem is not unlocking within my commendations.

And now again it didn’t grant me my commendation for Forerunner…

Anyone?
