Hi,
Thank you for using Telefication.
It’s the first time I hear about that problem.
In code level, I just send a message for new orders in thank you page after order completed.
But I think woocommerce uses WordPress commenting system for internal orders status and send email to the administrator as a notification.
It is possible Telefication send some messages with same content if notification for Email, New Order and New Comment enabled at the same time.
