ADIsimPower ADP238x parameters

I am using the ADIsimPower ADP238x tool for an ADP2381 buck design.  The "Thermal Performance" block on the spreadsheet shows the package thermal resistance is ~183C/W, but the device data sheet shows this is really 39.48C/W.  The higher number is used to calculate temp rise at the regulator, which (I believe) is now incorrect.

Can the parameter on the tool be corrected?  Have I missed something fundamental?

thx
