2D Object stuck on nothing

I'm trying to make some basics mechanics on a endless runner, but for some reason, my objects are getting stuck on nothing.

(This box is the UI canvas)

It look like my objects cannot pass the "0" position. Weird. Anyone have any idea on how to fix it?

 

Your Image in Canvas can't go (i think bcs i m not pro in canvas / ui) out of canvas, if you want a collectable diams système you need to create GameObject like prefabs and instanciate it by script

 

Already Fixed ^^ Thanks, it was a problem in the code that was moving the diamond. I removed 1 line of code, and worked fine <3
