Ultimate Facebook plugin duplicating events

Hi there.

On the site mentioned above, I am receiving duplication of events. Not sure what's going on. See screenshot. Doesn't always happen so can't figure out why. http://www.centrocbd.com/events-centro-cbd

On the home page, I have the events plugin (separate to the events page) with a slice in my pho code to restrict it to two. I have removed it before and his is not the issue. Facebook advise it is an issue with the plugin??
