This is for v6.4.3...I hadn't tested in prior versions so am not sure if this is lingering or new. Also, I searched the tickets and didn't see if it was listed already.

See attached comments in the Add-in spreadsheet. Corresponding stream in DWSIM file format also attached for reference.

The density values generated in the Excel Add-in are incorrect. The units on both Molar and Mass basis are kg/m3 (would expect kmol/m3 or mol/m3 for the Molar basis).
The units on specific volume calculated on a Mass basis are incorrect. Should be m3/kg.
The values for internalEnergy, helmholtzEnergy, and gibbsEnergy are incorrect.

Comments in attached cells highlight my suspected issues in the unit conversion calculations.

Thanks!
