Bug: event-page shouws event twice!!!

Hi,

I’m using a custom page for event (changed in settings) I noticed that by adding 4 lines, the event-detail page on the font of the websites shows twice! With twice, I mean the entire event data (map, name, category, etc.) twice below each other. This problem is gone, when the first reservation is made and confirmed.
