Adding an "a" at a citation

Hi,

Zotero is adding an "a" at the end of a citation in the text (it display "Moosbrugger-Leu, 1967a"), but there is only one reference for this author and for this year, there should be no "a". Why is that? And how to fix it?

Thanks a lot.
  • Chances are that you have two copies of the item in your library and have accidentally cited both. You should search for "Moosbrugger-Leu, 1967b" or just "1967b". If you find that you have two copies cited, open the editor and click the "Open in Library" button. Then, merge (don't delete!) the two duplicate items.
  • Fine, it worked perfectly, thanks a lot!
