How did you create your frcmod file? If I run the command:

  parmchk2 -i Mol-sm_m1-c1.mol2 -f mol2 -o frcmod.dac

I get a different file from yours, and it contains the angle parameters
listed above as "missing". I've attached my parmchk2 output.

Things to check: did you run parmchk2 as above? What version of AmberTools
are you using?
