Circle in Arcade physics cause not pushable

Hello,
When I set this.body.setCircle(50) for image, it is no longer pushable by other image. Why? Even if I call:

this.body.setImmovable(false);
this.body.pushable=true;

It doesn’t help…
Of course I set correctly colider and other stuff, because when I remove setCircle() calling, everything works perfect.
PS: With serCircle() - image which is pushing other simply stop, as if second one wall…
