Mission 7 not counting as completed?

I was running through the last few missions of campaign last night to finally finish up the story. So, after I beat mission 7, The Composer, I noticed the achievement for finishing the level didn’t pop. While I was a little confused, I just shrugged it off, thinking i’d just replay it later.
So, I finished the final mission and the 'chevie for ‘Midnight’ unlocked, and I patiently waited for my ‘Complete Campaign’ achivement. Alas sadly, it never did. I remembered ‘The Composer’; and sure enough, when I checked the mission select option in the campaign menu, it didn’t say I had completed it.
Not really too mad, I just loaded up mission seven again and blew through it on normal. Still no unlock. Hell, it still hasn’t said I’ve even completed it!

So, anyone else having this problem? If so, any solutions?

same exact thing happened to me, says I’ve only made it to the bravo checkpoint when i know ive done the whole thing. i even went back and did it from that checkpoint and it still says i havent finished it. not very happy and dont know what to do. and halo waypoint says ive finished the game on legendary but halo says i havent finished composer.

Bump because I’m seriously confused. Hopefully the issues thread can help out…
