Bome to my Yaeltex Controller - only certain CCs will light up button

I’m not sure if this is a settings issue inside BMT or my yaeltex midi controller. I am able to send a note on via CC 26 or CC27 to my midi controller’s button (assigned to CC 26 or CC 27) so that the button will light up. But I cannot get the MIDI controller button to light up if it’s assigned to other CCs. So far in my testing I can also use CC15 on Channel 4 not on Channel 1. I can get any button to light up as long as I use those CCs and a particular channel. I’ve used MIDI Monitor to spy on destination of controller and Bome MIDI Translator is translating whatever input into whatever CC I assign to the output but my Yaeltex controller will only light up if the button is assigned to (as far as I have tested) CC26, 27 (on channel 1) and CC15 (on channel 4)

This is really strange.

Any insight would be awesome!
