How do you edit pathway to menu item (events) when incorrect?

on industrynetwork.net.au when you click on Events menu item you get Nothing found message. This has only just happened was working fine previously (events still appear on a vertical slider).
If hover mouse above Events menu item you see http://www.industrynetwork.net.au/events/events/ Extra events in pathway seems to be problem. If I manually type just http://www.industrynetwork.net.au/events/ I see events.
Where do you edit path to remove extra "events"?
Have granted Support Access in case needed.
