District system is working, but, it keeps appearing on the screen. Help?

So, I want to make like a District System with Region3 and when you are going into a specific area, a GUI should pop up. It works, but, it keeps appearing after 5 seconds on the screen, which I don't want to. It's a local script. Anyone knows how to fix it? I've tried to do it with debounce too, but it didn't work.

local DistrictsWorkspace = game.Workspace:WaitForChild("Districts")

local Found = false


debounce = false

while wait(1) do

    for i, v in pairs(DistrictsWorkspace:GetChildren()) do

        Found = false
        local region = Region3.new(v.Position - (v.Size/2), v.Position + (v.Size/2))

        local parts = game.Workspace:FindPartsInRegion3WithWhiteList(region, game.Players.LocalPlayer.Character:GetDescendants())

        for _, part in pairs(parts) do
           if part:FindFirstAncestor(game.Players.LocalPlayer.Name) then
            print("Player was found!")
            Found = true
            break
        else
            Found = false
            print("Player wasn't found!")
            end
        end
        if Found == true then
            if game.Players.LocalPlayer.PlayerGui.Districts[v.Name].Enabled == true then
                game.Players.LocalPlayer.PlayerGui.Districts[v.Name].MainFrame.Visible = true
                wait(5)
                game.Players.LocalPlayer.PlayerGui.Districts[v.Name].MainFrame.Visible = false
                break
                end
else
                game.Players.LocalPlayer.PlayerGui.Districts[v.Name].MainFrame.Visible = false
        end
    end
end
