Filtering problem

Hello, I’m trying to make the calendar look and act like I want and I have a problem with filtering.
On your demo page https://demo.myeventon.com/?view=calendar-filtering I see a bar where you can filter on dresscode, location and organizer.
But when I use the exact same shortcode I only can filter on past/future events.
What do I do wrong?
Thanks in advance for your help and best regards, Arine
