Halo 3 Achievements Glitched

So i have completed the level Cortana with no skulls activated on the master chief collection 3 times in under par score time, twice on easy and once on normal. Not only have i not gotten the achievement for beating it in under par score time it also says that i have not played this mission at all it still says unplayed. i have tried closing the game and turning off my xbox and rebooting the mission several times in hopes that the achievements will pop up and it still has not. i’m resorting to these forums in hopes that someone can think of something that can help me get this achievement or maybe 343 industries will help resolve this issue…

Yes, also here on waypoint it doesn’t say that you have completed it in under par score. Not much to say, re try again or just wait for a future patch
