Multiple titanfall achievements at 100% yet still have not unlocked

I currently have three achievements in this game locked yet they are at 100%! I know of the ones locked is most likely the hardest achievement in the game and I would like to be credited for doing it. I also have two of the frontiers edge achievements locked
at 100% as well.

I would like to find a solution for getting these. The I killed them all has been locked for about two weeks now. I have tried clearing the cache. I have called and had no luck on the help from the phone support via Xbox.

Achievements are down... again

I have around 6 achievements I unlocked yesterday in Halo Spartan Assault that have yet to unlock. I got 100% in them and nothing. Though after the achievement issue was fixed, I unlocked other achievements, but these are still locked at 100%, even as of
now.

 

After latest preview update Achievements for Titanfall won't unlock

Haven Victor & Export Victor or TitanFall still not unlocked for me. Sitting at 100 percent.
