Using Zotero for Footnote: Converting to .doc or .docx, Footnotes Format Changed.

I’m using LO 4.4. I was working with Writer, and using Zotero to make my footnotes. Since my thesis advisor is Microsoft Office user, I have to convert my work to .docx. The thing is my format of footnotes are changing when I convert the document to docx or doc. For example: (1) I have superscript number format in odt file, but it changed to be regular; (2) in each footnote I have two numbers; and (3) there is additional tab.

Does somebody know the solution? Thanks
