Email order confirmaton text

I am trying to modify the text of the confirmation email template that the user and guest receive after placing their order, but I already modified the text in:

Dashboard / System / Messages/

Customer Notification Email
Guest Notification Email

But when the confirmation arrives the text of the email has not changed anything, what am I doing wrong?

Thanks in advance!

Hi again Raul,

I have already helped you on this via ticket system. The reason because wrong setting of default language that you use on your site.

All is working properly now.

Sincerely, Giang
