Need help with inconsistent forms styling WordPress Soft reject

1.Still, inconsistent forms styling:
This is the 4th time I have got this soft rejection.
but I can’t understand, What I have to do with this.
please help me.

May be they said keep both field background white or same color.
Another thing keep all field height same.

form all fields and form field level should design in the same style as like field background color, border style, field height etc. In screenshots reviewer focused different background color in different fields.
