Reply to Akai LPD8

Hi guys got an Akai LPD8, made my own mapping for hot cues, and now I want to map the knobs to fx, but for some reason when I map one of the knobs, It does what I wanted it to do in the mapping, but also controls the volume fader for some reason :/

Also I noticed that all the other knobs do something in traktor and I havent mapped them to do so anything yet.

Any suggestions ?

Also any suggestions on ways to get better at cue juggling ?
