Issues with Achievements

Hello there!
I’m playing Diablo 3 Reaper of Souls in my Xbox One and the following achievements are not unlocking:
“The Black Soulstone”; “The Coven Overthrown” and “Victory and Sacrifice”.
Those are all story related, that, theoretically could not be missed.
In the True Achievements site, I discovered that I wasn’t the only one having this issues.
