Wrong E-Mail template sent out after generating label

Hi,

when the customer paid his order and we generate the DHL Label by pressing the GENERATE LABEL, the customer is getting automatically an email with the DHL tracking number.

The tracking number is a good idea, only that the wrong email template is used for that.

the customer is getting the content of the “order confirmation email” template what he got after he ordered but before he paid:

in detail that means:

we pressed the GENERATE LABEL button.
This email went out:

1) on the top is the tracking number – OK
2) below is the notification for the customer to pay the amount to the bank account below. that is wrong!

but the customer paid already, thats why we are generating the label.

please look into that. thanks in advance
