Profile Color Selection Problem

A new profile was made for a simple moving head. Apart from Pan, Tilt and Intensity it has a 'split' channel whereby White is 0-9, Red 10-9, Green 20-29 and so on. In my moving light control screen I can see and use the intensity and P&T. To their right is a little panel (table) with all the colors in the profile listed. But its stuck on white! I can't click in say red or green. Back in the Tombstone display I can enter a value in the color field to change the color.
