Hi,
It looks different because the context is different (and the template too).
You're displaying the module into a special menu handle by your template.
After that, the demo template is customizing the "panels" differently than your template.
You can still use the setting "use simple ul/li" in order to not use the Joomla "panel" system but classical ul/li HTML structure. The rendering would be more classical I think.
