That error is a standard error provided by the DJI software. It generally gets fined when waypoint flights are more than 30km apart.
Did you try deleting the defined survey area and trying again?
This will occasionally happen if there is still an active mission that was taken somewhere else. When you define a survey area, make sure that the boundary is around the area you expect. If it looks like the lines go way off to somewhere else there is still an active point elsewhere and it is attempting to include that.
Any time you come across something weird be sure to take a screenshot of it so you can give it to us to help. Otherwise we are just guessing at what might have happened.
