A family of Microsoft word processing software products for creating web, email, and print documents.
When you're troubleshooting Word, it's always useful to visit Word>Preferences>View and check All in the Nonprinting characters section. OK out and you'll be able to see any hidden formatting.
You can also try adjusting the style settings for Footnote Text. Just click on a footnote, then select Format>Style from the Word menu. The Footer Text style will be selected by default. In the Modify Style dialog, click on the Format button, then on Paragraph. Style formatting gets to every instance of a given style, not just the ones you were able to select.
Since you have already applied local formatting to your footnotes, you'll probably want to select them and reapply the Footnote Text style to them, or style updates will have no effect.
