In a LyX document I imported three references from jabref; two by the same author. These are shown in the attached source.png. Note that Aichison, J. 1982 and Aichison, J. 1994 are shown separately.
However, when compiled using pdflatex, those two citations are typeset as Aichison, 1982,4 rather than Aichison, 1982,1994 (see attached compiled.png). I need guidance on correcting the compiled citations. TIA, Rich
