Achievements not unlocking?

Games Halo: The Master Chief Collection
1

Anyone else? I was heading through h2 and h3 co-op with my buddy and I got about 75% of the applicable achievements and almost none of the progress recorded onto waypoint. To give an example, I did not get the achievement for completing the last level of Halo 3 and waypoint says I’m 43% through the h3 campaign and 0% through h2. Strange

Edit:
Just some additional info on my account background.

  • joined the insider build durring the last week and only played matchmaking
  • Xbox one account
  • Never played any of the campaign levels through the insider program.
  • Left insider content fully Installed and then installed the additional 73gb update which btw . . . -_-

I beat halo the mcc on legendary but some of the achievements are still locked and even if I replay the mission they still dont unlock for me.
