Spherical mode source magnitude scale factor

I have a spherical mode source created using TICRA grasp software and would like to modify its amplitude and phase offset when using it in FEKO. I defined a spherical mode source in FEKO and tried modifying the scale factor but the far-field plots does not seems to vary with respect to the change in the scale factor.

I have attached the .cfx and .sph (I have changed its extension as .txt) files. Can you let me know why the pattern is insensitive to the magnitude scale factor?

    Are you comparing the Gain or the E-field values in the far field plots (Gain is the default output when plotting far fields)? I would expect the E-field value to change but not the Gain.

    I am comparing the far-field directivity. When I checked the E-field value is modified due to the change in the scaling factor. Can you describe why the Gain or Directivity values don't change?
