Updated Service Program Description not passing to Receivables Invoice (R12.1.3)

We updated an Item Description in the Item Master Org (only org we use) and can see that the Description on any previously created Contract Lines is updated correctly to reflect the new Description.  However, when we run the Service Contracts Main Billing program and verify in the Receivables Interface Lines, the Description displayed is the Description of the Item when the Contract Line/subline was created and not the updated Item Description.  I cannot find where the original Description is stored to be passed in the Billing Program.

Any suggestions?  (NOTE: Because of the large volume of data we have, manually opening each contract to execute the "Cascade Attributes from Lines to Sublines" is not an option.)
