V3 Smart Controller

[TRW]

Hi All - When I go into the Flight Route Icon on the remote [the area that allows you to select how you want to display the route - "Normal", "Hybrid" or "GPS" mode] there are three options for any of the modes selected; Calibrate Coordinate, Show Flight Route and Import Geo Fence. My question is the Calibrate Coordinate selection shows "For Mainland China"...this seems odd, however I don't fully understand the functionality of the calibrate Coordinate selection ON/OFF. It just seems odd the default is Mainland China and no option to select anything else. Is this just a glitch? I have the latest firmware, remote control software, android software and Autel app software, etc..
