What contact is shown on the Collections Dashboard?

On the Oracle Fusion Collections Dashboard, Delinquent Customers infotile, there is a column "Contact" that shows the contact of the customer bill-to site.

In case the site has more than one contact, which contact is displayed?

I can empirically say that it does not show the contact marked as Primary and not necessarily the one having "Dunning" responsibility, so what is the logic behind it?

I would expect it shows the contact with "Dunning" responsibility, which is the one receiving the dunning letter over e-mail, but that's not the case.

Thanks and regards,
