WeeWX knows of three 'pressures', you can read about them here <https://github.com/weewx/weewx/wiki/Barometer,-pressure,-and-altimeter>. If WeeWX knows any one of the three it will calculate the other two. For this to work properly you need to know which of the three pressures your station emits and the emitted pressure needs to be fed to the corresponding pressure field in WeeWX. Ideally, station or gauge pressure should be used as it is the raw pressure from the sensor and has not had any corrections. If the wrong pressure is fed to the wrong WeeWX pressure field the WeeWX calculated pressures will be incorrect and no amount of StdCalibrate will correct it.
You have not described your system setup, eg what driver are you using? how is it configured - what is weewx.conf? By default the Seasons skins displays pressures using the WeeWX barometer field. You can alter this if you want by editing the Seasons skin config file, skin.conf, and adjusting the various [DisplayOptions] config options (essentially replace occurrences of barometer with the pressure field of your choice). Note that if you don't get the pressure feed into WeeWX correct you will still likely see significant differences between WeeWX and your console no matter what pressure you select.
