How to clear the Flight Data map screen

I am testing endurance by flying a repetitive flight plan with photographs. After 2-3 iterations the map screen becomes very cluttered and I cannot see where the aircraft is any more. Is there a way to clear the screen of previous paths and photograph points while in the middle of a flight, but to continue to trace the new paths?

I am running 1.3.44 and Plane 3.7.1

Thanks for any help
