This issue occurs with MS Office 365 and zotero plugin.
Steps are:

3: Click "Document Preference", select "Multidisciplinary Digital Publishing Institute", hit "OK" to close Zotero - Document Preference dialog box.
4: Click "Add/Edit Citation" and choose any existing reference.

Against the expectation, the document shows the error message, "error: citation/ bibliography is wrongly placed in index area, please delete the placed citation/ bibliography in index area".
Does anyone has a good solution?
