Why can't I delete a Pantone Swatch color in Illustrator?

[Jimmy Papas]

When I select this color from the Swatches panel, the "Delete Swatch" icon is greyed out.

It may be imported with placed file.

Turns out I have placed links (Photoshop format) that have Pantone colors in them (through channels), so the Pantones were automatically imported into Illustrator, and that's why you cannot delete them, unless you delete those links, or you delete the Pantone from within the PSD links.

THANKS...my solution was to copy (x) the items. Close the file.

open a new blank document- placed the copied files (v) and then saved over the name file.

Deleted whatever hidden stuff on there.. but yes, thanks for the reason why it was doing that.
