Author and editor names cause most of the reported problems in EndNote.

If you see strange author entries in your finished bibliography, like the ones illustrated below, check each EndNote reference separately

To avoid these problems:

First names displaying in in-text citations

Where there are multiple works in a reference list by the same author, you should make sure that each author name is entered identically in the Endnote library (copy-and-paste the author's name to make sure they are identical). If your author names are not identical, then the in-text citations will be formatted to differentiate between different individuals by displaying first names as well as surnames.
