Additional Information (DFF) from Text Attachment not appearing on PO

Since the last Quarterly Update, we are experiencing an attachment related issue with purchasing documents.

Additional purchasing information captured in Descriptive Flex Fields (DFF), that are saved in an attachment against the requisition line, and then as an attachment on the purchase order line, is not being extracted to appear as additional information text on the Purchase Order form sent to the supplier. The supplier is still receiving the PO, but it is missing the critical information from the attachment.

See attachment for screenshots. We have raised an Service Request for this with Oracle, but were wondering if other users are experiencing the same and/or have a solution. Any assistance is appreciated.
