In order to exclude invoces that are in dispute from the dunning schedule we set another dunning procedure (an invoice level procedure - a procedure doing nothing) on the invoice the customer has questions about and we 'Pause Dunning' on the disputed invoice.

The regular dunning procedures are customer-level and have the 'Allow Override' checked.

This worked for a while and these disputed and 'Dunning Paused' invoices did not appear in the 'Dunning email sending queue', which is the expected result.

However, recently (unclear since when) these paused invoices appear in the dunning sending email queue result too.

It would be great if someone has an idea why the behaviour of the dunning module appears to be changed and how to prevent dunning paused invoices to appear in the sending queue.
