You are absolutely right, there was no flat electron generator enabled. The reason is that the new decays were not recognized as Dalitz-Decays (hardcoded in PData.h).

I did the following changes in PData.h (IsDalitz):
      int d = makeStaticData()->GetParticleBaryon(id) &&  // Delta0 Dalitz decay?
	  ((makeStaticData()->IsParticle(i1,"dilepton") && 
	    makeStaticData()->GetParticleBaryon(i2)) || 
	   (makeStaticData()->GetParticleBaryon(i1) && 
	    makeStaticData()->IsParticle(i2,"dilepton")));

      return (pseudo&&eeg) || (pseudo&&mumug) || 
	  (vector&&eepi) || (vector&&mumupi)
	  || D0 || Dp || pn || NS0 || NSp || d;


now it should print:
Info in <PDalitzModPlugin::ExecCommand>: Model <NS11+_dalitz> uses dGamma/dM for the branching ratio
Info in <PDalitzModPlugin::ExecCommand>: Model <NP110_dalitz> uses dGamma/dM for the branching ratio
Info in <PDalitzModPlugin::ExecCommand>: Model <ND130_dalitz> uses dGamma/dM for the branching ratio
Info in <PDalitzModPlugin::ExecCommand>: Model <NS110_dalitz> uses dGamma/dM for the branching ratio


and:
[ND13+_generator_p_dilepton] Dilepton generator {/generator}
