Stats are Not Being Recorded

I went to check and see how close I was to 50 missions so I could pop in a clan tag and found that all my stats are at 0 as if I’ve never played the game at all. Went into Career and Options, Career, Stats, Halo: Reach. Every category is all 0’s. I also have not been getting achievements, I am pretty sure. I am playing on PC via Xbox Game Pass.

Not to bump, but I also just noticed I am not getting achievements.
