WooCommerce is not sending the right E-Mail

Hey guys,

I have the following problem:
The point is that I offer advance payment as a payment option, i.e. the customer receives a bank account and has to transfer the money there. To do this, I created an email with the relevant data and this should always be sent out when the order in WooCommerce is “Waiting” after the order has been placed. I was able to link (see screenshot) that this email is linked to the order status “waiting”.
Nevertheless, the standard order confirmation is always sent to the customer. This causes confusion because the order is there described as paid. So I need help to make sure these E-Mail I created will be send out if some uses the payment option “payment in advance” or “by bank transfer” call it as you like.

Thank you!

Alex
