Halo Waypoint Draetheus V Archive bug

I am trying to enter codes in for Draetheus V-Recruit section but it continues to come up ad locked. I know that I have the achievement and the correct code but it still denies me access. I really need this code to work for a character in a machinima my friend and colleague are putting together. Please help.

The Recruit, Prodigy and Mjolnir / Able codes are only for those playing on Windows or Windows Phone. You’re looking for Flying colors which is the equivalent for Xbox 360 / Xbox one
