“Login” text befor Login Form

It is no big deal, but i want to understand. When i open the login-page there is a text “Login” writen before the Login-form starts with the <label> for Username an Passsword.

In Source-code it is only a text-line
Where in the template is that placed, because i don’t want anything else to be writen there. On the Edit-Page i only entered the shortcode [theme-my-login] nothing else where i can see, where this “Login” comes from.

THANK YOU
