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?
PHP 7.2.9 on different sites
JEM 2.3.0dev 2.0M and specials with Joomla! 3.9.3 stable on livesites
