Error in the atmospheric pressure

I have an error in the atmospheric pressure data that might appear in the change from 37 to 38 build. Still occurs with 39
The Vantage screen gives 1014.2. WD shows 1016.5. However Weatherlink and Cumulus give the values of the console.
Attached graphic information where you see the jump in the line and as it remains, more or less, 2 hPa higher. In the data log day, the impact occurs only in the pressure data.

Windows XP Service Pack 3, Pentium Dual-Core CPU [email protected], 1.96 GB Ram
Davis Vantage PRO2 vireless
Virtual VP
Cumulus
Weatherlink
Weather Display, WDL and WeatherMap Live

Best regards


Is a modification to inadvertently check Control Panel / CWOP / Altimeter Barometer Setup / Use this for WD barometric pressure reading.
Sorry
Cheers
