ScreenGui DisplayOrder isn't working properly

Hey there devs, I have recently found out that DisplayOrder the property under a ScreenGui isn’t actually working like its suppose to.

[My issue]
In the image below you will see that I have a loading screen screengui with a DisplayOrder of 10 and in the other image you will see that I have another screengui named UI with a DisplayOrder of 1.

My issue is that you can click the buttons that are in the UI screengui which has a DisplayOrder of 1 while the loading screen screengui has a DisplayOrder of 10.

[What have I tried?]
· I tried making the DisplayOrder bigger for the loading screen screengui and smaller for the UI screen gui
· Didn’t think of anything else I could do ngl

I would appreciate help / appreciate to know if this is a actual bug. Thank you!
