[GNC] Credit Note to pay bill

[Smartner Finance]

Here are 2 transactions...
1. Bill from a vendor on 01 Jan 2022 for say $100
2. Credit note from the same vendor on 02 Jan 2022 for $100


I continue to receive bills from the vendor each month and I continue
to pay them off from a credit card.

Every time I open GNUCash, it showws the Bill and Credit Note from 01
and 02 Jan 2022 in a Due Bills reminder window. How do I stop these
reminders from appearing for the Bill and the Credit Note. 

Can the credit note be marked as payment again the bill?

Regards,
Prince
