Object with physic?

Hello , i hope someone will be able to light me on this point :

when i creating some object , it’s working good i have the object with physic i can interact with it.

But some object i create are vanish when i hit them ( just by simple collision when i walk in)

like some container model , the big one is like not moving at all , the middle one is vanish when i touch it (even a low touch)
and the small one is reacting good on physique i can push it with a car , it’s not vanish.

so one some object who are almost the same , are fixe , other are moving good and some vanish on first contact.

so why ? and is there a way to change their property for make them not vanish ?

Did you set the collision?

Unfortunatly yes i try with and wihout,

when i set no collision i simply cross the object like a ghost , when i set it on and i touch the object it vanish with a spin.
