Reply to APC20 LED Mapping Help!

Hello all,

First of all I am relatively new to Traktor and DJing in general so forgive my beginner jargon. Secondly, I have been ripping my hair out over the last few weeks trying to figure out how to get the LEDs mapped on my APC20 in Traktor. I have tried tons and tons of things but I just can't seem to get them to work. Attached is an example for the Sync button. What am I doing wrong?
