If you receive a warning that an invoice has the same invoice number as a previously sent invoice (that was sent within the last year), you can get more information by clicking the Duplicates  button located below the information box in the Invoice Check step.

Then check the box for "Approve duplicates" if you want to proceed and send the duplicate.
Otherwise, you can delete the selected invoice.

In the Duplicates field under Invoice Action, the number of duplicates for the invoice will be displayed.
