Exported file in odt format from Google Docs, opened in LO: Cannot create proper footnotes in LO

I am using Ubuntu 14.04 LTS with LO Version:, Build ID: 420m0(Build:2). I have a 250 page manuscript which I have written in Google Docs. It is ready for the final formatting, adding headers and footnotes, and then exporting as PDF for sending to the printer to produce a book. But there are certain limitations in Google Docs due to which final formatting cannot be done there. For example, the header does not permit for having different text on left and right pages, whereas LO has this facility. So I have exported the file from Google Docs into the format odt, and opened the document in LO to complete my formatting.

The problem I am facing is that when I create footnotes now in LO, there is supposed to be at the bottom of the page a solid line above the first footnote which delineates the footnotes from the normal text of the page. That solid line is not appearing. Also, there at the bottom of the page, the number of the footnote is supposed to be set off from the text of the footnote. That is not occurring; rather the footnote number and the footnote text abut each other with no space between them-- unless I manually insert a space.

I have tested this when creating a file natively in LO and it works fine. The problem only arises when I export in ODT format from GDocs.
