The 'direct import' from ScienceDirect to EndNote for book chapters causes problems in your EndNote Library. If you try to import more than one book chapter the references will be duplicated several times.
Many books that are available in ScienceDirect are also available in Scopus. You could try this route to avoid the problem with the import in EndNote.
This error has been reported to ScienceDirect.
