Nicepage PHP web site form submit HTML tage error in template

Hi,

I've discovered the "Send email with PHP Script" contains two < /head> tags after each other that is causing unformated emails to arrive in my inbox. see below the two < /head>.

I'm using Nicepage Desktop version 4.8.2
Where is the PHP email template located to edit this template?

This is literally what the email looks like.
