Hi, It's not only in JEM, but there's a problem with old and archived events. In the Search Engines you find them on top, because from history, they have much more clicks than new events. So if you have events which are every year, you have to search in the deeps of the engines to find the newest event.
How can we resolve that?
I think the simplest way ist, that old version of the event are not available anymore on the web page.
So the archive should be hidden/disabled on frontend.
