Incorrect Acre Calculation Problem

I have a geodatabase with polygon features. The Shape_Area field is output in square feet and the conversion of square feet to acres is [ Shape_Area/43560 ]. When using the calculate geometry option I am not getting the acreage output from the formula [ Shape_Area/43560 ].

 

I have looked at several different articles both here and on the ESRI support pages and I'm not sure where I have gone wrong. Currently I am using the formula output for acreage [ Shape_Area/43560 ] rather than the calculate geometry field and I'm not entirely sure this is the most accurate method or if it's 'right' to use in analysis of these areas.

I have of course checked to see if my projection and calculate-geometry are not geodesic.
