Create Class with Android Studio 3.0.1

I'm using android studio 3.0.1 and I'm trying to create a new class in my App-> project. java-> com.valhondo.delgado.mibasedatos. Here I try to create a new java class.

Name: DBHelper
Kind: Class
superclass:
Interface:
Package: com.valhondo.delgado.mibasedatos
Visibilyty: public
Modifiers: None

When I give OK I get this error:

  

Unable to parse template "Class" Error menssage. This template did not   produces Java class or an interface

What do I still need to put and how do I put it so that the class is created?

Thank you.
