Komplete Kontrol & S49 Mk2 button assignment issue

Hi,
Working with Komplete Kontrol & S49 Mk2 kybd. I am trying to assign button 12 to a switch function in Arturia MiniV. That button appears to actually be sending data as knob 13. this with all other plugins that I am running. Can anyone check this and respond as to whether you see this also or not.
Thanks,

KK: 2.3.0(R177)
S49: 0.5.9
PC Win 10
Studio One 4

OK, after further research, I think the problem is associated with Studio One or the KK VST. Arturia MiniV standalone and KK standalone work correctly.

Just tried this in Cakewalk by BandLab, works. Must be something with S1.
Edit:
For general reference. OK, this is what I think is happening. I assigned button 12 to CC#26 (this is the default for the G-Force MiniMonsta to toggle the noise switch on/off). The KK mapping in S1 has the buttons mapped CC#112 thru 119. The knobs (2 pages) are mapped CC#14-29. (decimal values, the actual files show the address in Hex). So, when I press button 12 on the S49 (sending CC#26) the S1 mapping is rerouting that to knob 13 (CC#26 in the mapping file).
Edit:
Got the buttons working, struggling with the knobs.
Got rid of the KK S device, kept the KK DAW device and made a new device. (New Keyboard, assigned the KK -1 to the receive from).
All good, now to play.
