CMYK PDF export not correct?

[RickX]

When I export a .xar file to PDF, the CMYK seems to be not exported the right way (in XaraXtreme).

For example if I have a red square with the values: C 0% M 100% Y 100% K 0% and export it to PDF, then in the PDF file when I use the PITSTOP inspector to check the color values the CMYK values are: C0% M 100% Y 52% K 0%?

see attached examples.
Any solution to this? thanks.
