Missing achievements on GFWL

[Mikau]

Greetings

I've played all the way through AC, but one thing I noticed, was that certain achievements didn't register on GFWL. I have 38 of 54 on Steam, but on GFWL, I only have 35 of 54.
I was connected to GFWL every time I got the achievements, and I was also connected every time I made any progress towards one.

What makes it even more strange, was that I saw all the achievements pop up, along with it's twin on Steam. Only exception, the Steam version actually registred.

Yes, I'm well aware that GFWL is garbage. No suprises there.

Anyone else have this problem?
