Default Color Palettes in Edit Fill

Hello!

I have an annoyance and would really like to know how to fix it.  When I select a color for a fountain fill in the Edit Fill window or in Window>Dockers>Object Properties, it reverts back to Pantone Solid Color if I even click off that object.  New object?  Start all over. 

I’ve also tried making the changes and selecting Tools>Save Settings as Default.  It's frustrating when I am using the RGB palette for all other objects and would like to be able stay in that palette family throughout my design. 

Does anyone have any suggestion on how to correct this?

Thanks!
