I don't follow your last paragraph at all.
But never mind, I'll show you what to do.
this is a Kontakt channel,, Stereo to Stereo. This is the designated communication with that instance.
It should do what it says on the tin, in so many words.
I have not used Kontakt for a mono out, ever. This probably doesn't do any mono, as you see but 32 and the limit is 64 for "Kontakt".
However, I'll indicate what I do for an instrument which is outputting both stereo and mono by default, next.
