When I notice that a reference was somehow incorrectly entred by the library (source) and I have already cited that reference in my document I have no luck updating it. I manually alter the reference in my endnote library and then choose update bibliography. I end up with two references to the same journal article and if I choose the update one then I end up with two entries in my reference list as well.
For now, I am checking references before I cite them and resorting to changing the plain text document after finishing the report. I hope to resolve this problem before I write longer reports, and require same references in many papers…any help would be appreciated.
