No fly zone. How switch off this option?

Ground Control Software Mission Planner

Hello!
I would like deactivate “No fly zone” option in MissionPlanner. How i can do that?
I can’t find settings for this option. The big yellow circles covered very big areas and mostly only give the advice “be careful”.

Thanks Andras!
I tried to do that many times).
And it started to work suddenly. Perhaps this function works without connection with plane.
