        this.buttons = [            {                text: 'Save',                action: 'save'            },            {                text: 'Cancel',                scope: this,                handler: this.close            }        ];
        this.callParent(arguments);    }});

Thanks for the report. Can you please post a test case which reproduces this issue?

Looks like you are missing some CSS or your custom CSS is overriding ExtJS default CSS.
Rebuild the app and try again.
