Warping Constant using AISC member

AISC members have a warping constant (Iom or Cw) = 0 using the member from the AISC database. (see below).

But when I use this member with the CSA S16-09 design code, I get results that assign a value to Cw (see below)

Where is ROBOT getting the value of Cw?

It is calculated 'inside' the steel design module either based on formulas form the selected design code or the general ones for the declared section type. E.g.
