Bindhitbox does not work again after bone removal

Let me explain, I currently have a model which has a bone named leg0 and its subhitbox is named b_leg0hitbox

When spawning the mob it contains these skills

spiderboss_spawn:
  Skills:
  - effect:particles{particle=cloud;amount=125;hS=1;vS=1;speed=.01} @self
  - bindhitbox{m=spider_boss;p=b_leg0hitbox;t=spiderboss_leg0;delay=1} @self
  - hitboxconfig{m=spider_boss;p=b_leg0hitbox;pass=0.3;delay=1} @self

And this is the mm mob of its subhitbox

spiderboss_leg0:
  Type: VEX
  Display: '&6'
  Health: 50
  Faction: Spider
  Options:
    Silent: true
  Skills:
  - skill{s=[
      - submodel{mid=spider_boss;partid=leg0;submodelid=spider_boss;subpartid=leg0;remove=true} @parent
      - signal{s=SpiderBossSignal} @parent
      - signal{s=SpiderBossLeftLeg} @parent
      - effect:sound{s=entity.ender_dragon.hurt;p=1.3;v=1} @parent
    ]} ~onDeath

Once that, I have a skill that when you kill it, it proceeds to execute this skill to supposedly regenerate, but when you do this, the subhitboxes stay on the ground and the bone does not regenerate

SpiderLeftLegsLoop:
  Skills:
  - submodel{mid=spider_boss;partid=leg0;submodelid=spider_boss;subpartid=b_leg0hitbox;remove=false;delay=6} @self
  #
  - bindhitbox{m=spider_boss;p=b_leg0hitbox;t=spiderboss_leg0;delay=8} @self
  - hitboxconfig{m=spider_boss;p=b_leg0hitbox;pass=0.3;delay=8} @self
  #
  - setvariable{var=caster.LeftLegs;val=4} @self
  - setAI{ai=true} @self
  - setstance{stance=spiderboss_default} @self

(In the example I use the same actions but with an OnInteract)
