I am not familiar with this brand or model of camera, but the norm are dashcams record in segments, and all the time, if then something happen some of the footage go into a folder for events.
Many cameras today have the ordinary movies folder where the regular footage are, and then a folder named RO ( Read Only ) for the event footage to be safe from deletion inside.
I am not sure if these handle footage the same, there are some that for instance will not allow you to choose segment size and so may only do 1 minute video segments, i generally prefer 3 minutes myself if choice are there.
It could also be a setting option, though it do seem rare to me that a camera will only save events, most cameras default just record all the time, and then if G sensor or some other trigger is used it will save a event.
You could try to reset the camera to default, that option should be there in the menu / App, i assume it would be set to default record all the time.
