Skulls found but missing

I found all the skulls in the campaign but it says on my career that i have found none… Fix please?

I also have the same problem.
If you check my list of achievements for Halo:CE - Anniversary, you will see that i have the Headhunter Achievement, proving that I do have all the skulls.

Can somebody please Fix this? Thank you.

Yeah, I have done them too and they dont show up even though you unlock the achievement… seems like the people at waypoint dont read any of these posts , because it still is not fixed

That happened to me with the Halo 4 Terminals. I just went and found them again, and Waypoint updated. It might have something to do with being connected to Xbox LIVE.
