Mythicmobs to mmocore placeholder issue

Here is the problem. I am trying to make a custom skill, but the placeholder doesnt seem to detect, or return anything when i put it into the function. Here is the MythicMobs script

Implosion: Skills:

• damage{a="<modifier.damage>"} @LivingEntitiesInRadius{r=5}
• ignite{ticks=100} @LivingEntitiesInRadius{r=5}
• effect:sound{s=enitity.blaze.shoot;volume=1.0;pitch=0.5} @LivingEntitiesInRadius{r=10}
• effect:particles{p=flame;amount=500;hSpread=5;ySpread=5;speed=0;yOFfset=0.5} @Self

and here is the MMOCORE script

mythicmobs-skill-id: Implosion

name: Implosion lore:

• 'Deals &4{damage} &7Fire Damage to'
• 'enemies within &4{range} &7blocks of'
• 'the caster, lighting the enemies on fire'
• ''
• '&e{mana} Mana Cost'
• '&e{cooldown}s Cooldown' material: STICK damage: base: 10.0 per-level: 2 range: base: 5.0 per-level: 0.25 mana: base: 10.0 per-level: 1.0 cooldown: base: 8.0 per-level: -0.1 max: 8.0 min: 1.0

so is this a glitch or am i doing something wrong?
