How to remove horizontal lines

@achlomon0

I’m sorry to see that you did not get any response. These borders are due to the theme’s default table style. You may wish to add some style rules in the Custom?CSS area of your theme or of the Footnotes plugin to override theme’s rules, probably like so:

.footnotes_plugin_reference_row {
  border: none;
}

Eventually force:

  border: none !important;
