Answer: Remove field codes creates a copy of the document, since this operation is not undoable. With EndNote X and earlier, EndNote did not copy the Styles and Headings associated with the document, because these are kept in the template (like Normal.dot) and not in the document itself. Divorced from the template, the document styles appear to be removed. Note this is not an issue you should encounter in EndNote X1 or later.

It is possible to remove field codes manually if "Remove Field Codes" is not working for you.

Note: Removal of the field codes, either by the EndNote tool or the manual process described below, will permanently break the "link" between EndNote and the current copy of the paper. If after removing field codes you need to further edit your references using your EndNote program, you will need to return to an original copy of your paper with the field codes intact.
