How to make it work?

Hello everyone, I have problem with button to tycoon. I created new button, but i added 2 parts and decal. Decal and second part won't remove/disappear. I tried to add in script lines, which should remove them, but don't work.

Here is long script: (It's from berezaa tycoon kit)

script.Parent:WaitForChild("Buttons")
for i,v in pairs(script.Parent.Buttons:GetChildren()) do
	if v:FindFirstChild("Head") then
		
		local object = script.Parent.Purchases:FindFirstChild(v.Object.Value)
		if object ~= nil then
			objects[object.Name] = object:Clone()
			object:Destroy()
		else
			print("Button: "..v.Name.." is missing its object and has been removed.")
			v.Head.CanCollide = false
			v.Head.Transparency = 1
			v.Head.Decal.Transparency = 1
			v.T.CanCollide = false
			v.T.Transparency = 1
		end
								
		if v:FindFirstChild("Dependency") then
			v.Head.CanCollide = false
			v.Head.Transparency = 1
			coroutine.resume(coroutine.create(function()	
				if script.Parent.PurchasedObjects:WaitForChild(v.Dependency.Value) then		
					if v:FindFirstChild("RequiredGamepass") then
						local tycoonOwner = script.Parent.Owner.Value
						if tycoonOwner then
							if game.GamePassService:PlayerHasPass(tycoonOwner,v.RequiredGamepass.Value) then
								if config.ButtonFadeInDependency.Value == true then
									for i=1,20 do
										wait(config.ButtonFadeInTime.Value/20)
										v.Head.Transparency = v.Head.Transparency - 0.05
									end
								end
								v.Head.CanCollide = true
								v.Head.Transparency = 0
								v.Head.Decal.Transparency = 1
								v.T.CanCollide = false
			                    v.T.Transparency = 1
							end
						end
					elseif v:FindFirstChild("BadgeNeeded") then
						local tycoonOwner = script.Parent.Owner.Value
						if tycoonOwner then

								if config.ButtonFadeInDependency.Value == true then
									for i=1,20 do
										wait(config.ButtonFadeInTime.Value/20)

									end
								end
								v.Head.CanCollide = true

								v.Head.Decal.Transparency = 1
								v.T.CanCollide = false
			                    v.T.Transparency = 1

								v.Head.Decal.Transparency = 1
								v.T.CanCollide = false
			                    v.T.Transparency = 1
							end
						end			
					else
						if config.ButtonFadeInDependency.Value == true then
							for i=1,20 do
