Latest achievements not exhibiting up on Sequence X.

I’m enjoying The Power Unleashed (Xbox 360) on my Sequence X as a result of it's my favourite Star Wars recreation, and I wish to get 100% of the achievements.

Nicely, the final two achievements I accomplished, "Lightsaber Throw Mastery" and "Stormed," should not exhibiting up on my current achievements on my Sequence X, however they’re on the Xbox 360 achievements menu.

Why is that this?
