Artifacts Enchantment Doesn't Work Against Mobs with ImmunityTables Enabled

Summary

Currently I am using a Skill for an Artifact Enchantment, which runs a Damage Skills, dealing damage to a Mob upon attacking.

Enchantment Skill:

• skill{skill=SHARPNESS1} ?enchantlevel{level=1} @trigger ~onAttack Sharpness Skill:

SHARPNESS1:
  TargetConditions:
  - mythicmobtype{t=GHAST_BOSS} false
  - mythicmobtype{t=WITHER_MINI_BOSS} false
  Skills:
  - damage{amount=50} @trigger

The Mobs with Immunity Tables enabled, do not receive damage at all from the Skill, as if the Skill doesn't even proc, because no hologram is shown.

While Mobs with Immunity Tables disabled, do receive the damage and also the hologram displays the damage.

Intended correct behavior

Damage mobs with Immunity Tables enabled
