Language override did not work

Sorry guys, but creating an override to this issue doesn't seem to be working. The email still contains the standard text.
I have created an override using the joomla language override component and

Just noticed that the email contains the following text

Hello %s,



You have been added as a User to %s by an Administrator.

This email contains your username and password to log in to %s



Username: %s

Whereas the text in the administrator/language/en-GB/en-GB.com_easysocial.ini contains.

Hello %s,

This email contains your username and password which you can use to login to the site.

So I guess it is not from there the text is coming. Can anyone lead me in the right direction.
Thank you.
