The bug

Cave vines in Bedrock are implemented as three separate blocks:

• cave_vines
  • This is used for both the head and body types of plain vines
• cave_vines_body_with_berries
• cave_vines_head_with_berries

Whereas in Java, it's two blocks with a berries boolean block state:

• cave_vines_plant
  • For the body
• cave_vines
  • For the head

In addition, the growing_plant_age block state is just called age in Java.
