GUI 4.6 won`t show on camera

No matter what I do, add button, Image, text, UI will NOT show on camera/screen.
It did the first time, but camera was taking only lower left corner of main UI canvas. Like retarded…

I have set Screen Space - Overlay, this is what I want.

I did not know what was problem, Si I deleted camera created new one and now I dont see even one part of UI, and there are buttons, text, images etc. I dont see anything now…

HELP.

EDIT: You apparently cannot have your UI objects with canvas inside other empty object. So no parent, don`t see why but ok…
