I am attempting to add new elements to the "Sound" Item Type, but receive the following error:
----
Element #4: Name: 'Composer' already exists for element set #3
Element #5: Name: 'Librettist' already exists for element set #3
Element #6: Name: 'Conductor' already exists for element set #3
----
Previously, I created Items containing the following input:
Creator:
Composer: Giuseppe Verdi
Librettist: Joseph Méry
Librettist: Camille du Locle
Contributor:
Conductor: Carlo Maria Giulini
Could this be the cause of the problem?
Thanks!
