New event overwrites previous one

Hello Support,

I have been experiencing the following issue with the Event Calendar plugin for some time:

• I create an event for a specific date and it is displayed correctly, both in the list view and in the monthly view.
• When I create a second event, the previously created event is overwritten with the new data. Only the new event is then shown in the list and in the monthly view.

Unfortunately, I am not able to create multiple events.

Actions taken so far:

• WordPress version: 6.9.1
• Event Calendar plugin version: 6.15.17
• Events Shortcodes For The Events Calendar: 2.6.1
• Event Countdown for The Events Calendar: 1.5.1

I deactivated all plugins except the three Event Calendar-related plugins.
After that, I reactivated the plugins one by one.

The result remains the same: I can create one event, but when I create a second event, it overwrites the first one.

Do you have any idea where else I could check?

Thank you very much.
