ProfileMaker 5.0.5 and 5.0.5b for Windows contains a bug in the separation calculation. The CMYK curves start with a value higher than 0%. This bug only appears with the gamut mapping method "Logo Classic." This bug will be fixed as soon as possible.

For now it is recommended to use a gamut mapping option other than "Logo Classic," such as "Colorful," or switch to the Macintosh platform (the USB dongle used on PC works also on Mac).
