Spot Color in Document Palette

I am having a problem with Spot colors.  I use C1M100Y0K0 as my cut contour outline and have named it CutContour as required by Roland.  It works great! My problem is that somewhere along the line a second color with the same CMYK values but the name ColorStyle has found its' way into my files.  I can't delete the Colorstyle from the document palette because it says it is in use but - I haven't used it.  Two questions 1) is there a way to change the CMYK values of Colorstyle so it does not conflict with CutContour? and 2) is there a way to delete that color so it never shows up again?  It is troublesome having both spot colors in the document palette because I always have to check the color name before assigning it to an outline. Thanks for your help.
