MCC and Nightfall armor bug

Have the Nightfall armor from the Halo Channel and the two Mark VI sets from MCC. Can equip them but they do not appear in the REQ collection tab in-game. Any thoughts on why this is?

I wouldn’t worry about it unless you want a 100% collection armor still equipps fine, same with some of my weapons I noticed, about 20-30 of my equipment doesn’t show up there but I think the reason behind that is because I bought and opened the packs on waypoint and not in game when the game first launched
