In two places in my document, I cite a particular author's 2004 paper. For some reason, the citation appears fine, but is followed by a second citation for a 2009 paper by the same author, which is not cited anywhere in the document. Every time I refresh the citations, the 2009 paper is listed again until I get text that looks like this:
blah blah blah (author 2004)(author 2009)(author 2009)(author2009)(author 2009). Blah blah blah...
How do I fix this?
