Self Service Procurement (Redwood) – Agreement Removed When Delivery Date Exceeds Agreement End Date

We are facing an issue in Self Service Procurement (Redwood UI).

Scenario:
When the requester selects a valid BPA/Agreement in the cart and enters a delivery date that is later than the agreement end date, the system automatically removes the agreement reference after submission. As a result, the Purchase Requisition (PR) is created without any agreement linked.

However, in the Classic (old) Requisition UI, the system behaves differently. Even if the requester enters a delivery date that is beyond the agreement end date (for example, 1–2 month after the agreement end date), the agreement remains linked to the requisition as expected.
