how is events plugin really working?

I tried setting up the events pages in Multisite and multilingual with WPML.
If I create a page "events" and add the shortcode for calendar it does not show when the slug in settings is also /events...

When I change the slug the custom page shows up. But I can't get the prev/next to work. Short code instructions are poor and don't give me a clou on how the setup works best. The attributes don't mention prev/next buttons.

Is there a complete guide on setup the Events+ plugin?
