The lowest it will let me set a waypoint altitude is 6 feet, any way around this?

When flying a task the RTH alt defaults to 0, is that normal?

If I am just setting up some waypoints and do not want to fly the task at that time, I can find no way to exit “waypoints” without killing DJI GO 4 and restarting it again.  I am using a CS.

Any thoughts would be appreciated.

Why would you need to set a waypoint 6 feet from ground?

Why not?  Did it the other day for a low flyby.

Actually I want to go well under 6 feet. Taking photos of construction taking place under point of takeoff.
