My clone objects behind background

Okay basically I have two canvas's one which is my menu canvas (which is not the problem ) the other is my background canvas (which is ) I have clone objects that moves in and out of my 2d game but some of them goes behind my background canvas. It start doing this when I made the original objects a child of an empty object. I tried playing with the order in layer with my objects but it still does the same . I also tried tampering with the order in layer on the background canvas but it didn't work either. Another thing I tried was the render mode; I set it to screen space camera and put the main camera in the render camera and set the plane distance to 100 ; when I tried messing around with the plane distance (whist playing my game) all that happen was my background disappeared below: -0.3 and so on . It also disappeared above: 1005.03 and so on. Most of my objects appeared when I was messing around with the plane distance. How would I get all of my objects to appear above my background canvas? Thank you!
