Drone returns to Base after every 100 images or so

Hello.

I am mapping and large area using Mavic Pro 2 and pix4dCapture app on IOS. The missions starts normally and progresses as it should. However, drone returns home after every 100 images or so. Is this normal or is there a setting I need to enable in order for that to stop? Drone returns even if there is enough battery to continue or complete the mapping mission.

Please advice.

Thank you
