This damage can occur when:

• Importing either manually (IIF) or automatically from an integrated application.

To immediately resolve the issue, add a character to the duplicate name.

      • For Other Names, Accounts, or Customer messages, select the Lists menu.
5. Double-click the duplicate element name to open the Edit window.
