Master chief collection achievement issues

I've been having soooo much trouble with achievements lately. I got this game on release date and started playing halo combat evolved anniversary on Normal difficulty. Everything was going great. I was having a blast with the new game and shortly after
i completed the first campaign on normal, i decided to check achievements for the first time. I noticed that the achievements you get for completing the first 5 missions of halo combat evolved anniversary were bugged. They all have 100% completion and it is
stuck on "Done! Unlocking...". I looked this problem up that day and people just said it was a delay bug and it should pop within 24 hours. Well it's been about 9 days and they are all still stuck on 100% completion and i have not unlocked them. It has also
happened with other random achievements throughout the game but most of them popped within 10 minutes. I don't know why it is taking so long and i would greatly appreciate some help with this issue. Could somebody give me a way to fix this?

I know this is a stupid question but does the master chief collection have achievements?

 

Also i just downloaded the patch update that came out today, and it has not fixed it.
