When a section is imported from the Section Wizard, it is imported as a General section. When a General section is designed, the section is being consider as a equivalent I section by most of the design codes in STAAD.Pro, because the shape of that General section is not known for STAAD.Pro. This is why the design results are different. The only exception is EN 1993-1-1:2005 code, where you can instruct the program to design a General section as some standard shape (i.e. Tube) by using a design parameter GST.
