I work in InDesign, export to epub, tweak a thing or two in Sigil, and check in Kindle Previewer. I don't think I've changed anything in my settings or workflow, but suddenly the last couple of books I've worked on have started dropping my footnote (endnote) numbers (not the references in the text, but the numbers in the notes themselves). They show up fine in InDesign, but numberless in Previewer. This happens whether or not I make any changes in Sigil, so it's not Sigil causing the problem, but I'm wondering if it's something I could fix in Sigil...or of course if anybody has advice for InDesign or Calibre or whatever, I'd take that, too!
