Can't Select/Delete an Object?
I inherited a project and now need to delete some red lines that show up along the top and bottom of each page. I can't select the lines at all. They are clearly within the "Design Elements" layer on my file because when I toggle the visibility off they go away. However, I can't find any individual layer associated with the lines. I've done a test by deleting all text and objects within the file except the "Design Elements" layer to try to find the origin of these mystery lines. I'm new to InDesign so I'm sure this is a feature I don't know. Please help.
