Lone Wolf Legend achievement issues

Lone Wolf Legend is the Halo 4 achievement for completing all levels solo on Legendary.

Currently I am up to Composer. I have completed every level from Dawn to Shutdown on Legendary by myself. However, the achievement progress for completing the game on Legendary says that I am at 75%, while Lone Wolf Legend says I am at 50%, even though on my mission selection menu it says that I am up to Composer, I have beaten all levels solo on Legendary.

What is the problem here? Why is every achievement beyond glitched? Will I have to go back and play ALL levels on Legendary by myself, all over again? Just to find out what I’m missing? What if I do that and it still stay stuck at 50%?

Same thing happened to me if there’s not a fix besides replaying that’s not right as a fan consumer and loyal customer I’ve called Microsoft they can’t help I’ve massaged 343 gamer tags and Facebook profiles with no response

Well it started happening after I completed Infinity if I remember correctly. If I completed Reclaimer and Shutdown but LWL remains at 50% while the rest remain at 75%, that would suggest that those two levels are the culprits right? That said, I completed Reclaimer on Legendary again (ugh), and it is still at 50%.

I’m so done with this game and all of its glitches. I don’t mind replaying anything from the first three games but when I have to replay anything from the fourth, I get angry. I hate Halo 4.

Really wish they’d fix this, I wanted to complete these before do anything to do with matchmaking.

If you go on your halowaypoint account and go to service record you will be able to see which ones have registered that you beat solo on legendary
If they don’t say you beat it on legendary then look to see if it was completed on co-op

I completed the forerunner mission and ended up getting the bro hammer achievement which is to complete a level in co-op on legendary

I then realized that this mission was the only one that I didn’t complete in one go, meaning I started playing and then saved and quit and finished the next day. I think that saving and quitting has something to do with it

So if you could please check and see if it’s completed under co-op on your halowaypoint account and let me know if I’m correct in my assumption that’d be great! I hope this gets fixed before everyone trying to get this achievement loses their minds!
