UI not working

Hello I was following Bevy Lunex Book quick start guide and that's what I see (the green and yellow frames). What am I doing wrong here?

Also the book says I must have ui as children of my camera but the example just uses commands.spawn(). What is correct?

Oh and I use pan orbit camera plugin, maybe that has something to do with it.

    commands
        .spawn((
            SourceFromCamera,
            UiTreeBundle::<MainUi>::from(UiTree::new2d("Hello UI!"))
        ))
        .with_children(|ui|{
            
            //ui nodes
            
            ui.spawn((
                UiLink::<MainUi>::path("Root"),
                UiLayout::window_full().pos(Ab(20.)).size(Rl(100.) - Ab(40.)).pack::<Base>(), 
            ));

            ui.spawn((
                UiLink::<MainUi>::path("Root/Rectangle"),
                UiLayout::solid().size(Ab((1920., 1080.))).pack::<Base>(),
                UiImage2dBundle::from(assets.load("textures/Sample.png")),
            ));
        });

> Hello UI! == Window [pos: (x: 0, y: 0) size: (x: 100%, y: 100%) anchor: TopLeft] |  ||| Computed [pos: [0, 0, 0] size: [800, 600]]

I have the same issue, even 3d UI doesn't render anything (other than the debug outlines).
