Neither of these are bugs, but a side effect of how the color palettes are designed in ParaView. Let me explain the reasons for the two issues and we can then decide if the color palettes -- the way we have them -- need to be refactored.

<<Bug 1>>

When one clicks on "Edit Current Palette", you are simply editing colors for the "application palette" i.e. a globally maintained named collection of colors. You are not editing any of the predefined palettes i.e. Gradient or Black Background etc. When you select one of those from the Color Palette menu, you are simply copying the colors from those predefined palette to the "application palette".

When you restart ParaView, the last saved palette gets loaded. The bug is that when selects a different palette from the menu, it doesn't get saved in session, hence ParaView simply restored the last saved palette, which happened when you changed the background color to White.

<<Bug 2>>

When we implemented palettes, we added a mechanism to sever the link between a color and a palette color e.g. if you manually changed the "Edge color" on the properties panel, it severs the link with the Edge color on the palette and then changing the palette will not affect the edge color on the object. This is the same effect we're seeing here. When you change the "Gradient" property, it severs the link and hence changing the palette doesn't help here.
