problem in getting dispersion curve

I am trying to get the dispersion curve of a complex photonic crystal waveguide. I went through the tutorial "bandgap-photonic-crystal". I imported my geometry and changed the boundary conditions and other field to make it compatible with my model. I have the dispersion curve. The point is that when I change the k value manually (by hand for the study1) I get the almost resonable dispersion but the dispersion which is calculated by COMSOL in study2 seems not to be correct. It came to my mind whether in each step COMSOL can search for the localized mode. If so, why the results of both study are not identical?
I apperatiate any hint or comment.
