One 23c, 2x Xone K2 and Traktor pro 3 dilemma

Hi as the title suggests I am having some issues.

I am wanting to run 2x one K2's and a one 23c mixer together through traktor pro 3.
Right now I have a USB from my mac to my mixer and an a network cable from my X-link on the mixer to the outport of 1 Xone K2.

First I can't seem to get a response from either the mixer or the k2 with traktor (preferences have 23c as the external mixer and I have added generic midi for the K2's)

No idea where I am going wrong and there is little guidance online, secondly I would ideally like to run my 2x Xone K2's via the mixer and subsequently through traktor pro 3.. Is this possible? I would like to have 2 decks on channel 1 of the 23c and 2 channels on channel 2 of the 23c.. Again i am unsure if this is possible. My K2's are custom mapped to be used with traktor pro 2 but one serves as a 4 channel mixer and the other as an effects unit, I would imagine I now need to remap these but again cannot get the software, external mixer and midi controllers to communicate.

Hopefully some tech savvy heads on here can assist me.. Cheers in advance and hope everyone is keeping well during this.
