Dear Han,
 
Concerning the first question you are probably right. I think fundamental TE mode should be selected in the mode selection. I will contact my colleagues to confirm that this is the case and if so, we will update the article. Thank you for bringing this to our attention.
 
For the second question when you do the frequency analysis you need to first select the mode from the list and then enable the "track selected mode" option so that the calculation will be performed for the specific mode for all frequencies.
 

 
Best Regards,
Afroditi
