Getting Rid of the Line that Won't Go Away

As usual, excellent video!!!

I have a short, horizontal gray line in the left margin next to some, but not all numbered paragraphs. The line prints with the page. I can't figure out how to get rid of it; it is not the vertical line associated with edited text in track changes. When I hover over the line the small font/formatting menu appears with the drop down paragraph numbering icon highlighted, but it's not clear why that line appears next to some but not all of the numbered paragraphs. Help. None of these videos seems to address this, and I can't find any help with the Word help info for characters or lines in the margin.
