Why can't I prepare a dunning letter even though the customer has an overdue invoice?

We are having the same issue where we have customers with overdue invoices, but nothing shows in the Prepare Dunning Letters Process.  We went through and made sure all the settings for the Dunning Letter is set up as instructed in the Wiki.  Any assistance with this would be greatly appreciated!

Hello,

Please show the Dunning settings on the Dunning tab of AR Preferences.

How many days past due is the invoice in question?

If the Days Past Due on your Dunning Level 1 is 30 as shown above, the invoice must be 30 days past its due date before it will appear on the first level Dunning letter.

For example, an invoice due January 1 will be included on a Dunning letter that is prepared with Dunning Letter Date =  1/31 or later.  From the Help:

Hi, I am also having an issue with Prepare Dunning letters not including some customers. A customer has these invoices having appeared on a letter created and released 14/8/2024. AR Dunning preferences are normal 30,60, 90 with 3 days grace. 
 

Today 16/09/2024 the customer does not appear in the prepare. If I advanced that date to the 9/10/2024 then the customer starts to appear. How does Acumatica figure that the 9th is a good date to resume sending dunning letters ?
