This appears to be required in both 2.9.2 and 3x. The color controls in Extended 42 channel mode are not appropriately defined for LED Cluster1, LED Cluster2, LED Cluster3. The way the profile seems to be configured is that the 3 LED clusters are mapped to 1 color adjustment, instead of allowing control of the clusters individually, which is more consistent with the 32 channel Standard Mode. Please see attached manual starting on page 42.
Thanks!
