OpenStaad user table member properties in to excel

I am using OpenStaad to query a staad model. The issue I am having is that OpenSTAAD doesn't return section properties from members with cross sections from a user table. is there any way to retrieve the user table section values when using OpenSTAAD? I am using the below code (this works fine for section properties from the section database):-

 objOpenSTAAD.GetMemberProperties pnNextMemberNo, Width, Depth, Ax, Ay, Az, Ix, Iy, Iz

When the member is from a user defined table the member results are returned as empty.
