Events page showing yesterday's events

Hi, I have setup events manager to show future events on the events listing page, but it also shows an event from yesterday, so today (Saturday at 7:30am) it’s showing an event on Friday 12-6 https://www.yeahhackney.com/calendar/
I have checked my WP settings and the time is set to London (where I am)

Any idea why it’s doing this and how I can update it?

I’m WP 3.8.1 and EM 5.5.2
