Why cant I update a color palette?

So today I spent the afternoon teaching basic control to a newbie and found once again it is I who needs to learn....

ION 1.4.4

So I set it up and connected it to a few RGB(+Intensity strobe) lights I had lying around. 

Setup a custom fixture and patched them.

Setup ch 30 - 32 as group 1

Set the group 1 to Red

Record Color Palette 1 Red

group 1 red

all three lights red YEA. Lighting is fun.

After he programed a dozen queues I wanted to review patching so we added a forth LED.

ch33 Enter Update group 1

cool

ch33 set to red only using the encoders

Update color palette 1

Now when I press group1 color palette1 I expected all four lights to go to RED

No joy only ch 30-32 show the color palette

for some reason I can not add a ch the the color palette.

I am sure i am missing something but I am at a loss. 

This is repeatable for me on the 4 color pallets that I set up. 

What am I doing wrong?

I can re-record the palette or add the other fixture in blind I am just confused as to why I can not Update the color palette in live. 

Thanks for the help.
