Cannot remove random horizontal line in InDesign
For whatever reason, a random black horizontal line has appeared in my ID document, and I can't seem to remove it. It's appearing at the bottom of the text of the left-most column of a two-column page, yet it seems to extend beyond the column divider.
I've unchecked/ removed the horizontal line that appears in footnote style windows, and also unchecked any lines that might accompany columns (the little red line was made manually). Where is this black line coming from and how can I remove it?? Screengrab of black line included below:
