Double Interaction Per Interaction - 1.21.4 / latest dev mm

For some unknown reason items are doing 2 interactions per interaction, doesnt matter if interacted mob is mythic mob or default mob. There is no error on console either. Item:

testitem_interact:
  Material: STICK
  Skills:
  - m{message=doesthisAlso2times} ~onInteract @self
