Cant make a frame.visible = false ?

its kiddna hard to explain but i have 4 guis . the first guy has a button that when clicked it hides the first gui and it makes the second one visible and so on. the gui works fine when i just enable it from the start but when it make it open with a proximity prompt , i click the button , shows the second gui but it doesnt hide the first gui anymore (im sorry but its kiddna hard to explain, here are the scripts tho)

Local Script In The Gui Gyazo

local prompt = game.Workspace.Map.Secrets.ManilaRoom.Table.Interact.ProximityPrompt
local doc1 = script.Parent.Doc1

prompt.Triggered:Connect(function()
    doc1.Visible = true
end)

Normal Script Inside The Button Gyazo

local doc1 = script.Parent.Parent
local doc2 = script.Parent.Parent.Parent.Doc2
local button = script.Parent

button.MouseButton1Click:Connect(function()
    doc1.Visible = false
    doc2.Visible = true
end)

Normal Script Inside The Second Button (Just To Understand How It Works) Gyazo

local doc2 = script.Parent.Parent
local doc3 = script.Parent.Parent.Parent.Doc3
local button = script.Parent

button.MouseButton1Click:Connect(function()
    doc2.Visible = false
    doc3.Visible = true
end)

Gyazo#1

Gyazo#2

I Would Appreciate If Anyone Could Help Me , Thank You.
