[Events +] Events+ does not show all the events

Hello!
I installed Events+ plugin, it does not show all the events on the events page, which is : http://www.tribonet.org/conferences. It only shows 2 events, but there are more. It does show other events in the widget area though: on the main page, right bottom corner. I contacted live support, but they could not help me. They checked for plugin conflict and theme conflict, they could not find out the issue. The support access is open, please help me with this.
