Can't delete swatch. Shows up in all files. Invincible swatch.
Hello, I am using Illustrator 2023 27.7. I created a spot color swatch a while back and now I can't delete it (it is not present in a linked file, it even shows up in empty documents.) When I highlight it and delete it, it disappears for a moment and then reappears. I've tried to delete it with the delete key, dragging it to the garbage, selecting all unused swatches and deleting.... nothing works. I also opened its swatch options, changed it to a Process Color, changed other attributes, but when I click ok, the old spot swatch just reappears magically.
If I go to File>New, or New from Template and create a new file, any new file has this same swatch. Old files I haven't touched in years have this swatch now when I open them. It's everywhere and I can't get rid of it. Any thoughts? Thank you in advance for any help!
