Compass -> Orientation, doesn't save

MP 1.2.92 build 1.1.5111.11703 with APM 2.0 running AC 3.1 Hex, Windows XP SP3, German Version

Initial Setup -> Madatory Hardware -> Compass -> Orientation “APM with OnBoard Compass” radio button doesn’t save. There is no orientation selected once APM gets disconnected/connetced again. All 4 radion buttons come up empty again.
