Solved Different GUI position on differents resolutions

I am working on a GUI. I made it working on a 1600x900 resolution but when I test it on a different resolution looks like the GUI is on a different position. Like 2cm right.

Is that normal?

 

Ok. But if I use a 100% width, it will on the same position? Like InfoPanel.

 

Ok. Let me ask you other thing Wulf.
I am trying to make a GUI. On that GUI a have a text with a value that changes. Do you have any idea what can I do to reload that value on the GUI but without reloading the full GUI?

Code:

void CrearGUIGlobal(BasePlayer player)
        {
            var Elementos = new CuiElementContainer();
            var GUIGlobal = Elementos.Add(new CuiPanel
            {
                Image =
                {
                    Color = "0 0 0 0.91"
                },
                RectTransform =
                {
                    AnchorMin = "0 0.969",
                    AnchorMax = "1 0.995"
                },
                CursorEnabled = false
            }, "HUD/Overlay", "GUIGlobal");
            Elementos.Add(new CuiLabel
            {
                Text =
                    {
                        Text = Something,
                        FontSize = 13,
                        Align = TextAnchor.MiddleLeft
                    },
                RectTransform =
                    {
                        AnchorMin = "0 0",
                        AnchorMax = "1 1"
                    }
            }, GUIGlobal);
            CuiHelper.AddUi(player, Elementos);     
        }
