I created a journal entry for a credit on an A/P. This zeroes out several bills from them. But when I try go to the Pay Bills section in QB, I get one of two errors:

• If I select an invoice and click Set Credits I get an error that "You can't set discounts or credits to pay bills through QuickBooks Bill Pay Service"
• If I click one or more invoices and then click Pay Selected Bills it says "You can't use Quickbooks Bill Pay Service to make partial bill payments." This is true even if I use the entire credit and also show that a check will be created for the remaining amount due

How do I apply the credits? Every guide online says to use this this screen.
