Confirmation emails sent twice in two different languages and tracking number not being sent

When an order is completed I get order emails (as a customer) twice in two different languages - would this have to do anything with localization?

(edit: my bad, I used an email that redirected to the same email account)

Moreover, when I click on shipment options and add a new shipment package, add tracking, and click on notify customer, I dont get an email with tarcking number.

Any ideas?

edit2: The whole thing is messed up.

  • First of all, If you switch language to the admin panel, then the user receives confirmation in the language the ADMIN has in his admin panel. I hope it gets fixed in next versions

  • New Shipment does not notify the user. Anyone knows why?
