Hikashop - Transactional Emails: Order Status Change Notification

-- HikaShop version -- : 6.4.1
-- Joomla version -- : 5.4.3

Hello

I'm validating transactional emails and analyzing the behavior of two that have similar names and the same preview:

Order status notification
Order notification

I understand they are sent after an order changes status, from created order to confirmed order, for example.

To test this, from the seller panel (frontend), I accessed a received order and changed its status.

I validated the email accounts of both the seller and the buyer, but only the seller received the status change notification; the buyer did not.

Is this the expected behavior? Why are there two emails that look identical if one isn't sent to each participant in the purchase/sale?

Thanks!
