IF you were using Microsoft Word to compose the original document then you may have set the References Footnote or Endnote wrongly. Go to References section. This advice from Word Help:

Click References and then click the small arrow to open the Footnote and Endnote box.

In the Footnote and Endnote box, select the options you want. Before you click Insert, choose where you want to apply the changes—the whole document or the section you’re in.

To choose where you want to put footnotes, click Footnotes and then click Bottom of page or Below text.

To choose where you want to put endnotes, click Endnotes and then click End of section or End of document.
