You document is quite weird: the notes are styled Endnote but they appear where foot notes are expected. Even when I insert a new endnote, it goes at bottom of page. In principle, this is not possible according to Tools>Footnote/Endnote Settings.
I looked at the XML encoding and the notes are indeed classified as endnotes. However I noticed a high ratio of direct formatting. This made me suspicious.
The lists of styles, notably, character and list ones, confirmed my suspicion. Your document was initially written with M$ Word. There are important differences between DOCX (or perhaps RTF) and ODF in certain area to result in difficulties during conversion. I suppose this is one tricky case: your notes are now both foot- and end-notes and Writer does not know how to handle the case. Built-in commands are ineffective.
There is however a way to “fix” the document, which is acceptable only if the number of notes is relatively low (because the procedure is manual).
- right-click on the first note anchor in your text
- from the contextual menu, select
Footnote or Endnote
- click on Footnote radio button
Change is immediate, don’t press OK
- for all other notes:
- press the “next” arrow to access the next note
- click on Footnote
All your notes are now “standard” footnotes. But I don’t understand why the last part of the second note (at top of page 2) is detached from its first part and remains an endnote (and no longer anchored to anything in text). When I try to turn them into endnotes, they revert to their “zombie” not-footnote-and-not-endnote status.
I think that your document has been corrupted during the conversion.
