2d Animation bones don't show in scene

I rigged my character using unity 2d animation. When i dragged my character into the scene the bones don’t show. If i click on the sprite the bones flash on then off. What an i doing wrong:

Did you check to make sure that the Gizmos are enabled?

Thanks for your reply. Yes the Spriteskin gizmo was enabled The good news is i just solved the problem. In the inspector for the sprite I needed to check the “Use Layer Grouping” checkbox.

Yeah it bug, just close and open game object of the sprite and it will works
