Waypoint errors...

So I was looking at my Halo waypoint stats for Halo: Combat Evolved Anniversary and was looking at my skulls… according to waypoint it says that I have not found any skulls, yet, I have, I even have the achievement(s) to prove it… Can this be fixed? In addition, my waypoint stats on the xbox app states that I have not completed Halo Reach solo or co-operatively on legendary, which I have. . . I have the achievement to prove it as well… Can this be fixed?

We’re currently investigating this particular issue. Thank you in advance for your patience.

Thank you!
