Why Load (Pu) on Column is lesser than my actual (manual) calculations?

I am designing a structure in which I have applied the various loads but when I do analysis the it shows Pu which is very much less than I calculated 

I think it is not considering the loads due to slabs (plate mesh) for comparison see the RCDC calculations  and modelexcept beams final.STD 

and another question is that when i copy staadpro file it doesnot copy the whole data like parametric model data why?
