Event titles aren’t showing

Hi,

For a client website we encounter a problem: the events are showing on the calendar, but there’s no titles in the little blue bubble. The plugin is up to date (1.3.13.0), I tried clearing the cache of WPRocket, I also tried replacing the EventKoi block on the page with a shortcode. But nothing is working.

Can you help me with that?
