How to delete the endnote separator line

  1. Click the View tab, and then click Draft in the Views group.
  2. Double-click any footnote or endnote in the body of your text. The Footnotes pane appears at the bottom of your document.
  3. You can edit the color or style of the separator by choosing options on the Home tab, or, to delete the separator, click Footnote Separator in the Footnotes list, and then select and delete the separator line. However, it still takes the space of one line. I first selected the line and changed the Font size to 1 before deleting it.

Use the View tab to return to Read Mode, Print Layout view
I found it better to export the document from LibreOffice than to copy the file into an empty Word document (the endnotes then became hyperlinks with Roman number, which could not be changed).
However, endnotes became quite strange.
Had to modify the endnote anchor style to no superscript and then insert superscript again by hand for most of the references.
