Double eMail sending with different content and only one eMail template?

Hi folks,

I have a question, I use your plugin to send eMails to custom status. In this case I have an admin eMail with status “sended” https://prnt.sc/1uWIkXtDB56Z.

The problem is, that with this only one eMail will send out two eMails, look here the different eMails https://prnt.sc/nexfFFeZ32IP and this one https://prnt.sc/Jw3xB37BONRu. Here you can see the eMail Log, that 2 times are sending Mails with different content https://prnt.sc/Q4D-iJ7MRxj1

Why there are sending 2 emails instead of only one eMail, that is showing in eMail template. From where it comes the eMail without any product inside, how can I stop it?

Thx in advance.

Andreas
