Great to see that you @d0153 are already working on this! We have the same issue on our website https://www.bsg-sporttauchen.de/events/ running on WordPress 6.7.1 – might in fact be due to German/English translation issues.
Maybe our additional input helps you working on the internal issue:
- Changing from month view (default) to list view does not work.
- The left/right buttons for navigating through the months are not working.
- Clicking on the current month and then selecting a specific month from the drop-down menu works. 🙂
Thank you in advance!
