Roll a Ball tutorial - Pick ups stop rotating when i add more than one

I’m following along the roll a ball tutorial and when i add the first pickup and hit play it rotates just fine and looks great, once i duplicate that pick up cube and try to play again they dont move.

If i look in the scene view i can see the handles for the arrows moving around but the object doesnt move.

Video of what i mean.

Disable static batching on the cubes, they are being combined.
