Cross 1.6 Mapping issue

I noticed that there is one ontroll on the U-Mix Controler that is not mapped to the skin. The volume knob for the headphones.
When I turn the knob, the volume works, but the knob displayed on the skin does not respond.
This does not affect my mixing, but it would be great if it worked.
