STAAD RCDC, Ductile shear calculation in beam design as per IS code

Issue 1:

In RCDC, for Beam ductile design using IS code, how is the ductile shear being calculated?

I have referred to RCDC help file as well as RCDC Beam FAQ (Q.31) given in the link below.

I am able to grasp the technical intent, but unable to validate the formulas as the values which I am computing using given formulas (refer below) are not matching with the RCDC output. 

I also tried to find validation sheets for ductile beam design using IS code, but its not available. Only Non-ductile beam design validation is available. 

I am also attaching a typical design for reference and and would appreciate if calculations using the same reference can be demonstrated.

Issue 2: 

While transferring loads from STAAD to RCDC for beams, the loads are not transferred exactly. Some deviation (although not significant) is observed in them. What could be the probable reason for the same?
