When the game menu is spammed, it breaks?

I'm finding bugs with this and I came across a bug where when you spam it it's possible to have both guis down at the same time even with a debounce. Also, when you press the button to close the About/Credits menu, it works in studio but doesn't work in-game. I'm completely clueless on why this is, so any help is appreciated.

Menu = script.Parent
Play = Menu:WaitForChild("Play")
About = Menu:WaitForChild("About")
AboutMenu = Menu:WaitForChild("AboutMenu")
Credits = Menu:WaitForChild("Credits")
CreditsMenu = Menu:WaitForChild("CreditsMenu")

PlayClicked = false
AboutClicked = false
CreditsClicked = false
ClickedWaitTime = 2

function PlayButtonClicked()
    if not PlayClicked then
        PlayClicked = true
        Play:TweenPosition(UDim2.new(0.5, 0, 1.05, 0), "InOut", "Quad", ClickedWaitTime)
        About:TweenPosition(UDim2.new(-0.15, 0, 0.45, 0), "InOut", "Quad", ClickedWaitTime)
        Credits:TweenPosition(UDim2.new(-0.15, 0, 0.55, 0), "InOut", "Quad", ClickedWaitTime)
    end
    wait(ClickedWaitTime)
    Menu:Destroy()
end

function AboutButtonClicked()
    if not AboutClicked and not CreditsClicked and not PlayClicked then
        AboutMenu:TweenPosition(UDim2.new(0.5, 0, 0.5, 0), "InOut", "Quad", ClickedWaitTime)
        wait(ClickedWaitTime)
        AboutClicked = true
    elseif AboutClicked and not CreditsClicked and not PlayClicked then
        AboutMenu:TweenPosition(UDim2.new(0.5, 0, -0.5, 0), "InOut", "Quad", ClickedWaitTime)
        wait(ClickedWaitTime)
        AboutClicked = false
    end
end

function CreditsButtonClicked()
    if not CreditsClicked and not AboutClicked and not PlayClicked then
        CreditsMenu:TweenPosition(UDim2.new(0.5, 0, 0.5, 0), "InOut", "Quad", ClickedWaitTime)
        wait(ClickedWaitTime)
        CreditsClicked = true
    elseif CreditsClicked and not AboutClicked and not PlayClicked then
        CreditsMenu:TweenPosition(UDim2.new(0.5, 0, -0.5, 0), "InOut", "Quad", ClickedWaitTime)
        wait(ClickedWaitTime)
        CreditsClicked = false
    end
end
