Herelink controller buttons and Mission Planner Flight Modes

This will be long winded:
I’m in the process of configuring my herelink Controller v1.1 and MP 1.3.81 in a Cube Orange+. I’m somehow missing something. I’m trying to configure the short and long button configs. And though I’m able to configure the buttons in the controller using the herelink settings app, and confirm that they are functioning as configure, I able to confirm that they are functioning in the MP Setup in Radio Calibration, I’m unable to get the button function to show and function in the Flight Modes. If I set the para FLTMODE_CH to the matching channel for a single button function, the mode for the short and long press display and function, but this is only working for one channel and not for any of the buttons with changed channel settings (if that makes sense). So, what am I doing wrong. I cannot find any newer material out on the web that matches my newer versions. Thank you.
