Why cant I update a color palette?

Question

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.

Hi mate 
 To the best of my understanding, when using [update] to update a pallet, it will only record changes to chans that are already in the pallet. Try using [record only] instead. Since this is a selective record function ([record only] will only record manual values), it will add to the colour pallet and not record over it. 
 Alternatively, [33 record colour pallet 1 enter] will do the same thing (again, selective recording).... but is a few more button presses then using [rec only] 
 Hope that works for you Cheers BFJ
