Bug with the action "make a object"

Hello, when I use the action “create an object”, the object create does not appear visually even if it exists in the game because I created a PONG, and I made an event that will remove the ball when it disappears from the screen and will recreate the middle, except that the ball out well it counts to the score but I do not see it, how to solve this problem please

I think your object is behind the background, add the action “Z order” to your created object.
