When flying while using the DJI GO app it will show the height is at 1000 feet. When I watch the video with subtitles on it will show the baromater at most 300 feet. Which is correct?  Are both way off? I have the setting for measurement set to imperial and not metric. Perhaps the baromater reading of 300 is not feet and it's actually showing meters? If so, why if I have set to imperial?
