I was converting a print book file to an EPUB using the 19.4 updated version of Indesign. The print file had footnotes on every page.. In the conversion options box, I selected the option to convert footnotes to endnotes, but the formatting of the numbers in the EPUB were not consistent. Each footnote number that was on a new page in the original Indesign files was bigger than the other numbers (see screenshots). To attempt to fix the problem, I converted the footnotes to endnotes in the actual Indesign file before exporting to EPUB. This fixed the numbering issue but added an ugly, thick border around the endnotes (see screenshots). Reverting my Indesign program back to version 19.3, the conversion of footnotes to endnotes in the EPUB transfer worked correctly, and all numbering was uniform.
