Just tested and it worked perfectly fine for me on the latest version.
Thank you for your reply. I’m attaching two images: in the first one (before the update) two events are created, and in the second one (after the update) only one event is shown. I already modified the config file and even reinstalled, but had no success. Would it be possible to downgrade to a previous version, or would that cause any errors?
I appreciate your time and help. Best regards.

I am pretty sure it's working on the new release. I just tested it again. I think you're just missing something. Like maybe you didn't like the geofence.
As for downgrading, generally it is not safe. You should check what changed in the database and roll back those changes manually.
Currently I’m using Traccar version 6.14.4 and I have two geofences, one inside the other. With previous versions I didn’t have any issues: both entry and exit events for the geofences were generated correctly. However, now only one event is triggered. I’ve already added the parameter event.ignoreDuplicateAlerts to the config, but it still shows only one event when entering both geofences. Could you please help me? In earlier versions I never had this problem.
Thank you very much in advance for your attention and support.
