Pioneer DDJ RB master out level issue

hello,

i seem to have a problem with my master out:

1. if a twist the knob wile recording it changes the volume but on the final recorded track you can't hear the change, it's like i didn't even touch the knob.

2. if i move the know in the software while recording, i can hear it on the saved recorded file.

why is that?

the software with the knob on the controller are not synchronized. maybe it's a bug or it needs mapping or something? if so how do i do that?
