  Do you have a definition of TE mode? if so, please check if the "fundamental TE mode" is what you want. You can use "custom" selection and choose the mode you desire. Usually, choosing "fundamental TE mode" should be sufficient, by Lumerical definition.
  I am not sure what is the error message so I could not provide further help for this.
