I tested out the limits you suggested and found them to be slightly different. The mission would not auto sequence until I set the radius to 2 meters. When I tried 0.1 m (or anything below 1), the waypoints were created with a decimal but read back from the copter as 0 m. "1 m" was read back properly, but did not auto sequence. Then, 2 meters was the threshold. Thank you for the help.
