Halo 5 Gravelord Achievement Stuck on Unlocking

I’ve found each skull, and have 13/13 in my service record, but the Gravelord achievement is stuck at the ‘unlocking’ text. Has anyone figured out a solution to this? If so please post below.

Hey, there! Have you tried collecting one more skull? That’s what unlocked it for me. :wink:

This has also unstuck an achievement for me as well.
