crossfader jumping to other side issue

i have the behringer CMD micro and the numark dj2go

all midi buttons works BUT…
the crossfader only jumps from one end to the other.

is there a previous post (link?) to solve the this issue?
how do i set it up so the crossfader can transitions smoothly to the other?

Yes, this is one of the problem that we have been waiting to be fixed. It’s been months!
