Huge Gap Between Top and first Event

Out of the blue I just noticed that the main list has a huge gap between the top and the first LI of the list. I have tried everything with CSS to fix but can’t seem to find the solution. The site is responsive and when I move to tablet and smartphone size the gap dissapears but on regular browser size and larger the gap is there.

Here is the page.

Any help would be greatly appreciated!! Thanks!!
