Barometric Pressure Reading Way Low with my PWS, compared to nearby stations

About a week and a half ago, I purchased a new weather station, the Acurite Atlas with Acurite Access, to replace the old 5-in-1 I had....I love it so far, it is reporting to wunderground.   However, the barometric pressure listed there is much lower than it sure.   For example, a nearby PWS is showing it was 30.40, but mine is shown as 29.10.    I had adusted / calibrated it on the My acurite site as well as on my display, but why is this low a figure showing up on the wunderground page for my station, and now can it be corrected?

From the Accurite manual Pg 11 - Note: Calibration adjustments are only applied to readings displayed on the indoor display and stored on the optional SD card. If your outdoor device readings are also sent to My AcuRite, the calibration adjustments set in the indoor display are not sent to My AcuRite or Weather Underground.

It looks as if the uncalibrated data is being sent to Wunderground, which has no calibration option, unlike My Acurite.

This seems pretty stupid!! Have you emailed Acurite.
