Create Event with default value event type Closed

I created a few event categories. One of the categories is by default a Closed event (Private event).
What is de default value of the custom field of Event type: Closed event
Looking at the source this is value 2, I have entered this value as a default value but when I go to the front-end and create an event within the mentioned categorie the radio button of Event type is still on Open event.

Please helpd
