WP8 Xbox game Achievement not unlocking on W10M?

I tried to download some XBOX game recently on W10M on 950XL. I can get the achievement unlock notification, but I cannot see the achievement on XBOX app or XBOX.com, where it is working on my 920.

UWP XBOX game like Micorosft Mahjong or Bingo didn't has this problem, am I the only one?
