More multi parameter fixture questions

Teaching myself the Element. In patching a multi parameter fixture. in my case a K9 Pup: I am successful in patching the address to a channel (for example 11 to 11) I select the fixture from type, and then the console assigns the next 5 channels to the the address. Channels 11 through 16 are assigned to the instrument. According to the K9 manual, I should control intensity with channel 11, I do. That works, but I should be able to control red from channel 12, green from channel 13, etc.  But when I highlight these tombstones and bring them up, nothing changes.  They are also grayed out.

I'm sure there is something somewhere, but the brutal clarity of the ETC manual is preventing me from finding the answer.
