There is an extra empty line between the last footnote and the footer on every page. When I opt to show all hidden symbols, there are no paragraph markers or other unwanted symbols. How can I remove the extra space?

I have other files set up with the same parameters, and that extra space is not there in those files. But I am unable to see any difference between these files and the problem file which could account for the extra space.

I have tried going into draft mode and showing the footnotes; there also I could not see anything which would be causing the extra space.
