Why is bilboardgui still showing after disabled screengui?

hello, i am making a custom proxmimity prompt and while making it, i came across my billboard gui not disappearing from workspace despite the screengui being disabled?

i have to disable the bilboard gui itself and not the screengui, is this a bug or intended behavor?

I don’t see how these are linked? Roblox sees the two seperate GUIs as different things entirely, so of course you need to disable them both.

oh i was not aware i thought billboard gui served similarly to like a Frame under screengui, but i guess the tutorial i used incorrectly put Bilbiard Gui under screengui lol

A ScreenGui goes under StarterGui (actually PlayerGui) and displays GUI elements directly to the screen above everything else.

A BillboardGui goes under a part and acts similarity to a ScreenGUI, but moves around based on where the part is in the real world.
