When I clone a form it has the old title in the notification

I am trying to use the same form, but even after I change the title, it keeps showing the old in the confirmation email that it sends the users. They are confused and I am getting frustrated. Can you help me with this?

You may change the heading in the email notification by editing it. Please see the screencast below that can help you in changing the heading on the notification and auto-responder.

You may also create a new notification or auto-responder so that the form title will be added automatically as the heading. You may then delete the old notification/autoresponder once you feel that the newly added emails are working as expected.

Hope this information helps!
