Staad Plant Foundation: Why footing size too large by using IS code?; While US code give appropriate size!

1) Please Suggest modification, correction in my Staad Foundation file, for since I am Getting very large sizes in (approx Twice in Plan, 20 time in thickness).

a) Used IS code /IS 456, Si units, compared with US code SI units, Code ACI 318 -14
b) Loads : Only Operating having Vertical = -120 KN, Base Shear= 25 KN, Base Moment= 800 KN-m.

c) Results
i) Size by IS code: Footing base size in plan =7.90 m, Thickness= 7.900m(Abnormal high)
By US ACI code: Footing base size in plan =4.30 m, Thickness= 0.394 m.

ii) Overturning ratio: IS code 1.51 (first Load case) . By US code 1.703.

2) Also please inform under Calculation sheet generation how to get values of P, Wf, Wp, Ws in calculation of eccentricity:

3) Attaching SFA file (two), some screenshots for ready reference.

Thanks
