Party Payee Name not matching Payment Payee

Summary:

Party Payee Name not matching Payment Payee

Content (required):

We have Payment Request invoices that are imported though an integration that runs an FBDI loader. We noticed lately that one some of the Payments the Payee Name does not match the Payee actually printed on the check. As you can see in the below example, CIGNA shows as the Current Payee Name nad Party, however when you open up the Payment number link, you see that the Payee is now showing as CSI LIFE INS. We do not know how/where this is derived from...

We are trying to determine why this happened, and if there is a setup page we can see this somewhere. This "Party" is not setup as a Supplier. Any assistance would be greatly appreciated!
