lastest build Damage modifiers are not working

mob:

dummy: Type: HUSK Health: 1000 Damage: 1 DamageModifiers:

VENENO 0

weapon:

AtaqueVaraAprendiz: Skills:

projectile{onTick=[ - effect:particles{particle=reddust;color=#FBFAF9;amount=1} ];onHit=AtaqueVaraAprendizH;v=26;i=1;hR=1;vR=1;hnp=true;hp=true;sE=false} @Forward{f=999} sound{s=entity.evoker.prepare_summon} @self AtaqueVaraAprendizH: Skills: damage{amount=9;element=VENENO}

with this simple example acording with the wesite the "veneno" type of damage will be doing 0 to that mob, but is doing full damage, so whats wrong?
