my JD the dead world disk just spins around and the ball doesn't lock in there?? does this mean I don't have the mod?? sorry for the dumb question

The original version had the disc with slots in it that go to the edge of the disc which the balls fell out of easily ... The mod ( as pictured above ) has holes cut in the disc instead of slots which holds the balls in there like it should .
