Spalling reduction factor calculation and effective shear depth in shear wall

Hello, I have S-Concrete V.2024 in Canada. Therefore we are working with Canadian code, CSA A23.3. I have two observation that really affect the calculation for shear walls and now I am gonna share it hear to have my answer.

1-About dv, effective shear depth, I am wondering why in S-Concrete this factor would be design always with lower allowable factor saying 0.8Lw and it is not considering 0.9d or 0.72h.

2-About spalling factor, as per commentary in code, if we have flange at two extremity of a shear wall, we can ignore that reduction factor. as S-concrete has the option modeling I or C section, I am wondering why the spalling factor would not update in terms of magnitude or would not be eliminated.

Thanks
