Considering HE neutrinos produced at internal shocks induced by intermittent mildly-magnetized jets, we show that such annihilation suppresses the overall HE neutrino spectrum at $\\gtrsim 300$~TeV and produces a corresponding flavor composition of $(F_{\\nu_e+\\bar\\nu_e}: F_{\\nu_\\mu+\\bar\\nu_\\mu}: F_{\\nu_\\tau+\\bar\\nu_\\tau})_\\star \\approx (1 : 10 : 1)$ at source.
