Cash Receipts using "Remittance" method - discounts beyond grace period due date

When using the "Remittance" method to apply cash receipts, JDE is changing the dollar amounts and disounts entered if the invoice is beyond the discount due data grace period.

Does anyone know of a way to keep JDE from recalculating these amounts without increasing the grace period days?

We are receiving a "soft warning" related to Discount Earnable but when we accept these, JDE is still changing the dollar values.
