Ghost Recon Wildlands Achievements Not Unlocking Issue

Well, I have this issue for a long time, from a month later of the game's release, some of my achievements are not unlocking. I have tried to contact ubisoft, they said that they can't help, then contacted xbox support and gave me some basic troubleshooting
steps but the problem still remained. I even used this following thread : Achievement Unlocking Issues? -- CHECK HERE!! , but it also didn't work. I'm pretty sure I didn't do anything wrong to not unlock them. The achievements are
the following: The Whole Story , Mission Master , Legendary Hunter , Heavy Medals.

Ghost Recon Wildlands

Details have been released for the first update, which includes a Splinter Cell PvE mission that Ubisoft say is the toughest stealth mission yet in Wildlands. Until 16 May you can unlock Fisher's goggles.

Looks like they're bringing the Predator back for the weekend too.

Sam Fisher officially joins Ghost Recon Wildlands from tomorrow
