Can't correct return to vendor transcation in oracle fusion redwood

Summary:
Return to Supplier transactions are not visible on the Redwood Corrections page – documentation says corrections should be done there, but the return lines never appear

 

Content:
We are on Oracle Fusion Cloud SCM – Receiving, using the Redwood self-service receiving pages (Receive Expected Shipments / Returns / Corrections).
Scenario / issue:

 

A purchase order receipt is created (Receive + Deliver) for a PO.
A Return to Supplier is created from the Redwood Returns page (Create Return). The return is submitted successfully and reaches status Fulfilled.
When we open the Redwood Corrections page and search by the receipt number, only the RECEIVE and DELIVER transaction lines are displayed. The RETURN TO VENDOR / RETURN TO RECEIVING transactions are not listed at all, so the Correct action cannot be used against them.
