UI Scaling Issue

I am currently making User Interface for my game but it keeps scaling incorrectly in game. Does anybody know why this is happening?

I made sure to emulate to 1920x1080 resolution. (Fit to window)
I made sure it’s scale instead of offset.
The ScreenGUI is Global (IgnoreGUIInset is on)

unknown
Here is how it looks in studio (How I want it to look) - 1920x1080 emulation [FIT TO WINDOW]

Here is how it looks in game (Ignore the toolbar, I am talking in regards to the blue bar and green bar)

I have a 1920x1080 monitor.
Does anyone know the reasoning it messes up like this?
