Problems with achivements

Please help.
The game of Borderlands The Pre-Sequel Claptastic Voyags DLC for xBox 360.
On the day we went out I received two achivement DLC, which only I see .For other they are not visible! despite the fact that I have two achiwements every 15 point, then they are not counted for the whole.
At the present moment I miss only two achivement, and yet I have shown with 59/63 achivement .A properly should become 61/63.
I have completed every part of this series of 100%, and this would also wanting.

First, this is not really a tech support issue. The achievements need to be unlocked.

I can not help you get your achievements but here is a list of them. From there maybe you can determine which are missing and go after them.

good luck
