X-NUCLEO-LPM01A Board wrong voltage after calibration?

Hello,

I'm using the X-NUCLEO-LPM01A Board. Today I encountered a problem with the calibration. If I set the voltage to 3.3V and run a calibration I measure at VOUT only 3V. Without any calibration I measure the expected 3.3V. If I set the voltage to 1.8V and run a calibration I measure also 3V at VOUT. Without calibration it's 1.8V. Have you seen this problem? Or do I something wrong? Maybe I have to set the voltage after calibration again?
