Color palette problems on X6

Hi there,

I'm using CorelDraw X6 on Win7 Pro and I have problems with color (RGB&CMYK) palettes. I attacked print screen on my desk top and on right you can see what's going on. From the left, there is two palettes which I have created myself. My problems occurring in the third palette RGB and fourth CMYK. Pantone solid coated palette works flawlessly. I removed the program and installed it again, but this didn't solve the problem. Do you have any idea what's going on?

Thank you for your support!
