Hi Sara,
The command "?mde_num" returning the value 0, indicates that line 39 could not find a mode with a TE polarization fraction above the indicated threshold (0.95 in the example). So to answer your question, I suspect either a TE mode is not found in the reported modes, or no modes are found at all. A good approach to confirm this is by checking the results of FEEM>modeproperties. You should be able to see if any modes are reported and what their TE/TM fractions are.
Best,
Khash
