Mark VI Not showing up (2016)

Okay so i just got the “Your Journey begins” nd “Cairo Stations” achievments and after a while i have not unlock the Mark VI or the scarred version otherwise, so I thought it might be because its 2016? So i get into Halo Channel and launched MCC and launched Halo 5 to see if they sync, one way or another and still, no helmet. Anybody having these problem? Or probably had?

Even though you have the achievements, Halo Waypoint may take a bit of time to acknowledge that you’ve completed the missions. Give it a bit of time, then check again!
