Max: The Curse of Brotherhood Achievement glitched!

Okay so Im playing this game and in the game you get achievements for collect 6, 12, and all amulets. I just found the 6th one and collected it but no achievement was unlocked. My account still thinks I only have 5 of them unlocked. I seen people with the
same problem but only with collecting the evil eyes. How do I fix this? and does anyone having the same problem? thank you.

:)

 

Glitchy Achievements

My daughter beat Max: Curse of the brotherhood and didn't get the achievement for a certain spoiler

 

Xbox One Achievements Not Unlocking

Same for Max The Curse of Brotherhood. There is only one achievement I'm missing and it's locked at 100%.

 

I am having a similar problem, I completed the game and collected all amulets and evil eyes, but it shows 69 days left in the challenge "be among the first to collect all amulets and evil eyes"and not complete.

 

I've had a similar issue, but not with the amulet pieces, but rather gamerscore. It's showing as I did them, but three are no points added to my score as they are labeled.
