FB2 format has the option to show "Footnotes at page bottom" but it seems not working. In Book Designer view if you put the mouse in a footnote it appears as popup, but when exported to FB2 format, HanLin does not shows them at bottom in current page, not in BeBook firmware and not in HanLin one.
Do I need to do any special thing in Book Designer or HanLin to get them working?
