Dielectric slab example file

I have a few questions about the boundary mode analysis in a dielectric slab (which is also given as an example file in the model library).
1) In this model the slab can only propagate single mode (TE0), yet when "desired number of modes " is more than one in the boundary mode analysis, it finds more than one propagation constants. One of them is the desired propagation constant with respect to the selected frequency corresponding to the single mode's solution. I don't really understand what are the other values I get. Are they propagation constants of radiate modes?
2) I've sketched a wider waveguide which supports more than one mode, and I calculated the corresponding propagation constants. Then I used frequency domain to plot the modes in the waveguide, however I can plot just one mode. I dont have different solutions in the "results" for different propagation constants of the same frequency. so which solution does it plot? and also how can I plot the other modes?
Thanks,
Arie.
