I have successfully beaten every level of Halo 5 Guardians coop on heroic or legendary. The achievement all for one did not unlock. I went onto halo waypoint and it says the unconfirmed was beaten on easy and that guardians was never played at all on coop. My campaign tracker on the game itself says otherwise. What can be done. This is the last achievement I need in order to be at 100%!
My first suggestion would be to replay the levels.

Your game history on waypoint indicates you’ve only completed unconfirmed co-op on easy. You can see that here.
Unfortunately I had to replay the levels that halo waypoint marked as wrong. I now have 100% of all Halo 5 Guardians achievements!
