Halo 5 Achievements

I just completed Halo 5 campaign on legendary Solo but received no achievements what so ever for anything. I had checked the achievement progress, but it says it is at 93% completed and 15/15 completed? Any info on how to fix this or if anyone can see anything different on my service record would be much appreciated.

You may just need to wait a bit. I never had that issue so I wouldn’t know.
