I've used a template to create a customised form for myself.

However, when a form is filled and I get an alert by e-mail, I still get all the data from the template I've used and not the form I have created. This seems like a bug you need to fix.

So, the email is stuck with the old version of the form. What you need to do is to delete the email alert and re-create it. 

Here is how you can delete it:
