Cross section properties in Karamba

Hi everyone,

I have attached a photo result in table format obtained from Karamba. (fig3)

First I selected the cross section as in fig (1), and tried to obtain the properties result as seen in (fig 3) first part of the table. 

Secondly I defined the same cross section with the exact same geometrical parameters of the section as in fig (2), and tried to obtain the properties result as seen in (fig 3) second part of the table. 

Question : The geometrical parameters provided in karamba for the cross section are same, but the properties obtained are different. Why is that so?

Please let me know.

Thanks in advance,

Regards,
