How to do a frequency sweep of fundamental TE modes of a waveguide in the MODE FDE solver?

  Hi,
  
  I have been trying to do frequency sweeps for the effective refractive index for the Fundamental TE mode in my waveguide. I have been selecting the first mode that appears after calculating the modes and checking off the 'Track selected Mode' button. However, I am not sure how it is obtaining the results because when I go and manually enter the frequencies it is sweeping through, I get my fundamental mode to have a different effective refractive index than the one shown in the sweep. What could be the reason for that? Would I have to write a script to pick out the fundamental TE mode every iteration of the sweep? If so, how can I do that? I would appreciate any help, thank you.
