Duct Size Calculator Issue

I'm having an issue with the Duct Size Calculator. After I run it, the Extended Data reads the flow through the duct in cu m/s instead of cfm and similarly for friction. How do I change that? When I draw the duct it says CFM in the dialog box. Until I run the Duct Size Calculator, the duct doesn't read any flow at all. What am I missing, or how do I change the units in the Duct Size Calculator?

In fact, you don't need to concern the flow unit shown on extended data before calculation. It's just the default unit of flow, but after calculation, it's the definite unit.
