Bug with Events page

Hi.
I am relatively new to WordPress and ive been having an issue pinpointing what is wrong with my events page. It hides all my information for some reason once you click on the events tab. If you click it again, it flashes the information correctly but then hides it again. I feel like there is an issue with the code on the back end. How can i fix this? what do i look our for? We use the lemon chili theme

you can reference our site and the issue here
