Hidden paths - can't delete
I'm working with a logo file that was created by someone else and there's hidden paths (all squares) which seem to be used as guides.
I can hover over them to show (like below) but I can't select them or delete them and I need to get rid of them.
I have passed this to another company to cut from vinyl and it's cut all of the square too, even though you can't see them or work with them.
Anyone have any idea as to how to delete these?
