FX's,Mapping and CUE problem on DDJ-SX2

Hey guys. I just buy my brand new DDJ-SX2 and I love it! But I have some issues with it! 
1. My FX's don't work. Everything is turn on and set up,but they just don't want to work. macOS Sierra with Serato DJ 1.9.6 

2. Traktor scratch pro 2 (2.11.0 23) mapping problems:
2.1: I hear master cue even when my knob is turn left to cue. 
2.2: I try every mapping on internet,but nothing close to good.
Jog weel is not precise as in Serato DJ. Is there anyone who have some good mapping for Traktor ? Thanks,and sorry for my bad english.
