achievements not unlocking?

I did try MVP and One Man Army before and the behaviour is the same as for Landstalker; it unlocked the in-game accolade but not the achievement.

Can confirm MVP and One Man Army unlock ingame, but not in xbox

In fact, I can see now in the Xbox app, Wonder-Full's description has been changed to:

"Build 22 Cultural Wonders over several games."

Ah nice. That is good to know. Might be able to cheese it a bit.

Proof that it’s atleast possible to unlock everything in game.

Though shutting down your game and restarting it causes Falling Out, MVP, One Man Army and Landstaker to reset again.

Landstalker sticks for me but the in-game accolades aren't working properly. The problem is known and documented for about a year now with multiple patches having been published. I lost faith this will ever be addressed.
