I need to remove single full line separator between text and footnotes
without removing all of the footnote separators. How do I do that?
Switch into Normal View and go to View | Footnotes. A footnote pane will
open up at the bottom. Use the dropdown menu at the top of the pane to
access the separators--the short one is the Footnote Separator, and you can
copy&paste it so that the Footnote Continuation Separator (the full line) is
a short line instead, or delete, enter something else, etc.
I'm not entirely sure exactly what you want your final result to be, but
that should point you in the right direction.
