Sorry, don't know where to post. I have a problem with consistency with footnote with kepub and calibre. With the same html sometimes I have the pop-up (footnote 1 to 15) and all the other footnotes are just navigation footnotes (all the footnote >15). But for other book it's the first one and the other pop-up correctly.
ex with the footnote 10 (pop-up)
epub
Lapin<span class="footnote-anchor"><a href="part0049.html#amanuensis-note10" id="amanuensis-anchor10">(10)</a></span>
kepub
Lapin</span><span class="footnote-anchor"><a href="part0049.html#amanuensis-note10" id="amanuensis-anchor10"><span class="koboSpan" id="kobo.231.4">(10)</span
and with the 19 (no-pop-up)
epub
Mor<span class="footnote-anchor"><a href="part0049.html#amanuensis-note19" id="amanuensis-anchor19">(19)</a></span>
