RigidBody2D moves at Play (Updated)

Hi, I have a cube and when I insert a rigidbody or rigidbody2D and press Pause and then Play (so I can see exaclty what happens at the start) the cube moves even when the game is paused,

Edit: With RigidBody works but with 2D components doesn’t

What I do is to put a Cube with rigidbody2D and a Box Collider2D
and under it I put another cube with just a Boxcollider2D, when I press Pause and then Play the cube with the Rigidbody2D moves!,

I started a new clean project and the same thing happens.
