We have updated our algorithms to avoid such situations in new versions of Wialon.
Here is FAQ for previous versions:
"The reason is that if you control exit from several geofences in one notification, it is impossible to detect which geofence exactly was left. To have geofence name in such type of notification, you should create a separate notification for each of those geofences."
If you face this issue with Wialon Hosting, please, send us a request to firstname.lastname@example.org with example (notification name, unit name, goefence name, time of exit from geofence).
