Customer Invoices are Printed instead of Emailed

Summary:

Some customer receivables invoices are printed when they should be emailed.

Content (required):

When running Print Receivables Transactions, the child job spawned is "Print Receivables Transactions: Invoices" instead of "Print Receivables Transactions: Email Delivery." When I query ra_customer_trx_all, the column DEL_METHOD_CODE = PRINT_INV when it should be EMAIL_INV. I've checked several customers, and from the front-end customer screen, the settings appear to be the same, yet we're getting a different result. Can someone please provide some guidance?
