Hi,
You can see all the emails sent by HikaShop in the Customers>Emails history menu.
There, you'll also have the name of the email for each one, so you'll know the correspondance with what you have in System>Emails where you can edit them.
I believe that the "2. Payment is Confirmed" is the "payment notification" email. If it's not, then I don't understand why:
- you wouldn't receive, as the shop owner, the "payment notification" email when the order is confirmed
- you would receive another email from somewhere else (maybe the payment plugin you're using is sending the email without going through HikaShop's mechanism ?)
