Hi there,
Your domain looks right to me (the URL that appears in your browser bar), but I bet you are talking about the site title, right? So to update this, you can go to your Dashboard > Settings and make the edit there:

Just change the Site Title field to anything you'd like!
Does that help, or were you looking for something else?
