Hi,
Thanks for using the Events Calendar.
Here on the pre-sales forum, I’m afraid we do not provide technical support. I would ask that you take any technical support questions across to our wordpress.org forum – our staff scan it periodically and other community members may also be able to help out.
The Events Calendar
Or if you own the premium version of the plugin please post in the premium forums.
Having said that I took a look at the site and the event in question is a recurring event and a multiday event setup to start in October and run to June 2016.
So the plugin is working correctly as that event has started already, but not ended so it will show first.
Thanks again!
