No it wasn’t duplicated, all the events in the site were all set up the same way.
I tried not using the orderby shortcode and it displays in descending order fine. I think I might have to just leave it at that as it seems to be just this one event that I’m having the issue with.
Changing the settings doesn’t seem to have sorted the issue. The shortcode I’m using is: [events_list category=”demersal-working-group” scope=”all” orderby=”event_date”]
Here is the page where the issue is happening. It only seems to be this one.
