iOS Comile to PDF - Footnotes created as endnotes

When compiling a project to .pdf on iPad, endnotes rather than footnotes are created.

It would also be useful to adjust the margins of the output document as they are currently rather large (iOS default?).

Actually, in my case, the footnotes do not appear at all after compiling, not even as endnotes (on the Mac version, there is no problem whatsoever). Did I miss something?
