I’m very frustrated by this.
I’d finished the level on Legendary and the achievement didn’t pop.
So I ran through the level on Easy just to get the achievement and it still didn’t pop.
I have no idea what to do now.
I’d say nearly half of the achievements I’ve earned in the MCC were buggy. Usually I would get them a few minutes to a few days after completing their parameters. So sometimes you just have to wait.
343i didn’t seem too interested in fixing these issues regardless of what’s the cause since people still bring up such issues. I wish you best of luck.

Waiting has not worked for me, as I completed MCC on legendary as soon as it came out. The campaigns in MCC solo, legendary, are completed, show completed, but did not get credit for them. They show completed, legendary level.
Since I want the Helios helment and armor, I restarted with only the campaigns that did not register as completed legendary, as displayed on Halo Waypoint. I completed three campaigns today, but am only getting credit for two. This is ridiculous. I am open to suggestions… Waiting did not work for me, as I completed these months ago…
