your fields are numeric I take it... 0 is the nodata value for numeric values in shapefiles.  If you need to retain <null> then you need to save the results in a geodatabase.  Alternately, you must provide a conversion/replacement to represent null.  For example, -999 or some other number that doesn't exist in the data
