Games Halo: The Master Chief Collection

So…

I have found and Claimed every single skull from Halo: CE to Halo 3.
I have earned every standalone achievement for finding each skull!!
I have earned all three “find all the skulls in this game” achievements!!!

but the “Throne of Bones” achievement, which states that I must find all skulls from Halo: CE to Halo 3, is stuck at 97%.

whats wrong with This Game!?
i dont Want to pick up every skull a Second Time!

so what should i Do?
