My Phantom 4 pro v2.0 got into a crash not to long ago and I rebuild it. And calabrated everything form compass to the vison sensors. I calibrated all of the visson sensors on my computer and every vison sensor works when I boot up the drone inside. But when I boot the drone up outside the Backward and downward vison sensors give me a calibration error. Is this because I calabrated the drone vison sensors inside. Not sure why this is happening I could use some insite thanks.

I fixed the problem one of my backward vison sensors were lose so every time I calibrated it it would be fine until I went to fly it then it would move and through off the calibration.
