Confirmation email Title is wrong => Account Details for {NAME} at {SITENAME}

Hi All, im opening this post as my last chance, for two days im trying to figure out how and where its possible to change the title in the email what is sent by JFB after a new user is registered.
I found where can i change its body, in the language/en-GB/com_jfbconnect.ini over there i can change the body of the email, but i cant find any option to change the title of the email.

To start with i dont know why its like this: Account Details for {NAME} at {SITENAME} but anyway i thought if this linking is not working i will "hard code" and just enter my site name and instead of the variable username i will just put there hello.

But i cant find its place, any tip warmly welcome!

OMG i cant believe this, its working THANK YOU SO MUCH MELISSA, you are the best as always, i really cant believe its fixed!!!!!!

You just made my day!
