Custom main screen elements become offset in plugin

Godot Version

v4.2.1.stable.official [b09f793f5[

Question

I’m currently attempting to make a plugin that adds a new main screen panel.
I got the new screen to appear, but almost all control nodes/elements are misaligned in the actual screen.

2D view of control.

How the main screen looks in the plugin

Does anyone know how to fix this weird offset issue?
