Unattached Footnotes after Import docx file?

I have imported a large (400 pages) document. Especially in the first 150 or so pages, it contains “unattached footnotes”, written in square brackets in the text (just behind where the footnote should be). The linked footnotes in the inspector are underlined in blue, as if they were links. Why did this happen? How do I get the footnotes where they belong? There are over 200 of them…

It sounds to me as though something with the .docx file is messing up the converter; perhaps some formatting codes it is not programmed to handle correctly. I would try converting this to RTF using Word, first, and then see if that imports correctly.

Thanks for your answer. I have circumvented the problem by copying and posting individual chapters instead of important the entire document. That worked fine.
