Luban Settings for Artisan Dual Extruder

I am running Luban v4.7.0. I’m lost on one aspect. When trying to do dual colour printing, I can’t figure out why the settings are different for the Left Extruder than for the Right extruder.

The Left Extruder has, under ‘Recommended’ settings - Layer Height, Speed, Model Structure, Support and Adhesion Type, whilst the Right Extruder only has Speed. Am I missing a way to get more than just the basic settings on the Right Extruder? Even if I click More settings, the Right has a LOT less than the Left.
