Just something I have noticed. I have unlocked armore like the Nightfall, and they are listed as unlocked in my customizations. Unfortunately they are not listed in my Reqs as unlocked. Seems weird to have items available in one place but not the other
It is because you get the nightfall armor by watching nightfall, Armors obtained in this way, such as my mk vi appear in the customisation menu but not in the unlocked reqs list
