I just starting playing with Zotero to see if I would like to switch to it from my other reference program. I've integrated it with Word and like it so far. My only problem is, whenever I go to enter a citation, Zotero keeps generating two footnotes instead of one (two superscripts next to each other at the end of the sentence); the first note has the correct citation in it, and the second one just says {citation}. Am I doing something to cause this or is there a glitch in the program?
