Compass auto rotation

Hello.
After performing a Compass calibration with COMPASS_AUTO_ROT,2 , in Mandatory HW/Compass i find the external Compass with yaw 270.
But It has no orientation…
Anyone knows the explaination of this?
Many thanks

Same problem, same hardware, maybe faulty mag sensors? Or bug?
