Seems to work fine here.
Define "Editing box"
Sorry - "Swatch Options" box.
2 Pantone colors are "Un-Editable" - Swatch Name and Color type are ghosted.
You need to have the swatch palette open > click on the element that uses one of the Pantone colors > the swatch should be highlighted in your swatch palette, panel, whatever > you should see the CMYK triangular square in the palette > click on the CMYK icon to convert the color to process > should show up as a new swatch, if not, just drag it to the swatch palette.
Thanks a lot for the info - turns out it was an added spot color in photoshop - so once I merged the spot color channel into cmyk and re opened it in illustrator it worked!
