Hi Monica,

The original entry of the invoice may have originated in AP from Tasks,Pending Invoices.  Changes to an invoice that was recorded in Pending Invoices will still write to the same batch as the original invoice, therefore even the entries generated in a Change Invoices session will send to GL with the same batch with the same batch description as the original invoice. The Heading that you see on the GL Entries by Batch report is pulling from the Batch record.
