Trying to simulate physic but no physic body

I have a first trigger to spawn my Doll Bp , in my dollBP they are “Tete” in first and “Corps”,“SphereCou” next.
By default their simulates physics are disable.

I have a second trigger to enable their simulates physic … but it doesn’t work correctly… I have this error

My head, my neck and my body fall together, I would like they fall separately… I understand that my neck and my body follow my head but it’s strange because when simulate physic is enable by default and my doll spawn then they separate … And I don’t want to spawn my doll one piece by one piece (they are 27 pieces …)

Please I really need help …
