Spot Colorpalette - Bug or not

Hallo,

I create a new spotcolor palette with the name (for example) "my_color" and by using this colors in Draw I see only white.

Test:

-VIEW - Normal:  the color is visible in Draw and the PDF

-VIEW - Enhanced: the color is unvisible In Draw but visible in the PDF  (as Spot-Color with a false name)

-VIEW - Enhanced with Overprints: the color is unvisible but visible in the PDF (as Spot-Color with a false                         name)

Can handel CorelDraw CD-X3 and X4 only one Spot-Color Palette?
