Has anyone seen a Vouchered Payment Request ID be reused?

We're on PeopleSoft FSCM 9.2.36 and we use Fluid Payment Requests. Today a customer was trying to view an attachment from a voucher with source Payment Request. When she clicked on the Attachment link on the voucher, the File Name and Description fields indicate 'Reference Not Found'.

Looking into this further, we found that the Request ID that created the voucher was no longer associated to the voucher, and in fact, had been reused about 2 months after the original Request ID had been vouchered (original request was created and vouchered in Feb 2021 and now has a creation date of April 2021).

The Payment Request created in April was Denied and has no Voucher ID in the PS_PR_REQUEST record.
