I just compiled a fragment of an article I was writing, from markdown to docx. The command was: `pandoc -o alhazen.docx -F pandoc-citeproc --bibliography=bib.bib alhazen.mmd`.
I received a warning about a duplicate reference. The docx file contained several blank footnotes. When I replaced the second reference to `[@Alhazen1572-qk, V.9]` with an Ibid., the warning disappeared, yet I *still* get empty footnotes.
I have used 1.19.2.1, and also a nightly beta -- with the same results.
