Series 7 Watch Compass Elevation Inaccurate

When opening the compass app on the watch the elevation data is way off. My job has me 74ft in the air operating a crane. When I check the elevation against this it showed me as -6ft and 6 ft from sea level. At home it shows me 50ft up when I’m only 14ft up. What the heck Apple. Is there any way to recalibrate the elevation data or is there a software update to address this issue coming?
