Schep Omni Channel Midi Learn doesn't work

DAW : Maschine 2 / Reaper
Plugin: Schep Omni Channel
Windows 10 : 64 bit

Repo: If I right click on a control in Schep Omni Channel, I get an option to ‘midi learn’. However this doesn’t work.

I do the same process with Arturia V collection synths and there is no issue, which leads me to beleive that it’s an issue with the plugin.

I would like to be shown where I’m going wrong so I can control this plugin, else it’s useless to me.
