Yeah turn off "pressure is absolute" if you are not using station pressure (versus corrected barometric pressure, which is what it currently reflects in the picture).
I just came from Nevada (to Tampa) where I had my rifle dialed in at about 5K' DA. My zero did not change but my transonic range did. Also, if you do not change your zero here in Tampa, you do not have to change your "zero atmosphere" in Ballistic AE. Only change/update your "current atmosphere".
