I am having issues applying a journal entry to a vendor bill as a payment. I believe I have properly configured the journal entry to link back to the appropriate vendor, and I am able to select the JE along with the correct vendor bill on the Pay Bills screen, but when I hit save, NS generates a separate bill payment rather than applying the JE to the vendor bill.

I can apply the JE if I click "Make Payment" directly from the Bill and curiously, can make it work through the Pay Bill screen in our sandbox account, but I cannot seem to make it work in my production account.
