Hi.
It could be a Word specific thing. Sometimes people have issues with Word (secretly) reformatting elements as per its own styles.
You could try and open your docx file in LibreOffice (free / opensource). If the footnotes are then fine, you’ll know it is Word doing that. (In which case you’d have to tell Word how you want them footnotes formatted.)
