Maintenance worksheet not creating accounting entries

PS Accounts Receivable image 9.2.22

We have a customer with 2 items that we should be able to offset. The original item was a credit created at conversion time, later we created a debit to offset it. When we create the maintenance worksheet it all looks good, but when I try to create accounting entries, it creates a debit / credit for the first one, but not the second. We also tried creating the maintenance worksheet and just running AR Update - in that case it ended up in posting errors because the accounting entries were out of balance (because half were missing) Details attached.
