Hi. In the file you attached, no line shows up. That suggests that it is actually in a paragraph in the page header. Are you familiar with headers and footers? If not, double-click in the top margin of one of the pages on which the line appears. This opens another layer of the document reserved for repeating information in a defined section of the document. You should see a dotted line going across the page 1/2 inch from the page top. In that space, I suspect you'll find the line and should be able to select and delete it.

Let me know.

Best, Ulodesk
