External Barometer temperature

I have a Pixhawk (ArduPlane V4.0), because board got naturally heated during flight, on minimOSD altitude shows incorrectly. To fix this problem I connected extended barometer, that shows correct temperature and altitude on MP. I set external barometer as primary in Pixhawk settings. But minim OSD still shows internal telemeter, that is wrong.
How to fix it this problem?


Thank you.
