Why will this script that makes a button visible only work in studio?

I am trying to make a game but you need to complete quests to unlock the swords. When you complete a quest it will update a BoolValue and make the button to use the sword visible. You start off with the Starter Sword and the Holy Lightning Blade if you have the VIP gamepass. It is working fine in studio but it won't work in game.

Script that creates the values and stores them once the player leaves:

local datastoreservice = game:GetService("DataStoreService")
local odata = datastoreservice:GetDataStore("show")
local Market = game:GetService("MarketplaceService")


game.Players.PlayerAdded:Connect(function(plr)
	local show = Instance.new("Folder", plr)
	show.Name = "show"
	
	local HLB = Instance.new("BoolValue", show)
	HLB.Name = "HLB"
	local MB = Instance.new("BoolValue", show)
	MB.Name = "MB"
	local NS = Instance.new("BoolValue", show)
	NS.Name = "NS"
	local SB = Instance.new("BoolValue", show)
	SB.Name = "SB"
	local SS = Instance.new("BoolValue", show)
	SS.Name = "SS"
	local STS = Instance.new("BoolValue", show)
	STS.Name = "STS"
	local WS = Instance.new("BoolValue", show)
	WS.Name = "WS"
	
	local dMB
	local dNS
	local dSB
	local dSS
	local dSTS
	local dWS
	
	pcall(function()
		
		dMB = odata:GetAsync(plr.UserId.."-dMB")
		dNS = odata:GetAsync(plr.UserId.."-dNS")
		dSB = odata:GetAsync(plr.UserId.."-dSB")
		dSS = odata:GetAsync(plr.UserId.."-dSS")
		dSTS = odata:GetAsync(plr.UserId.."-dSTS")
		dWS = odata:GetAsync(plr.UserId.."-dWS")
		
	end)
	
	if dMB ~= nil then
		
		if Market:UserOwnsGamePassAsync(plr.UserId, 7483219) then
			HLB.Value = true
			
		else
			
			HLB.Value = false
		end
		
		MB.Value = dMB
		NS.Value = dNS
		SB.Value = dSB
		SS.Value = dSS
		STS.Value = dSTS
		WS.Value = dWS
		
	else
		
		if Market:UserOwnsGamePassAsync(plr.UserId, 7483219) then
			
			HLB.Value = true
			
		else
			
			HLB.Value = false
			
		end
		
		MB.Value = false
		NS.Value = false
		SB.Value = false
		SS.Value = false
		STS.Value = true
		WS.Value = false
		
	end
end)

game.Players.PlayerRemoving:Connect(function(plr)
	
		local show = plr:FindFirstChild("show")
		local MB = show.MB
		local NS = show.NS
		local SB = show.SB
		local SS = show.SS
		local STS = show.STS
		local WS = show.WS	
	
		pcall(function()
		
		
		
		odata:SetAsync(plr.UserId.."-dMB", MB.Value)
		odata:SetAsync(plr.UserId.."-dNS", NS.Value)
		odata:SetAsync(plr.UserId.."-dSB", SB.Value)
		odata:SetAsync(plr.UserId.."-dSS", SS.Value)
		odata:SetAsync(plr.UserId.."-dSTS", STS.Value)
		odata:SetAsync(plr.UserId.."-dWS", WS.Value)
		
		
		
	end)
end)

For example: the script that makes the Holy Lightning Blade visible (its parent is the button):

local show = game.Players.LocalPlayer:WaitForChild("show")
local sHLB = show:WaitForChild("HLB")

sHLB.Changed:Connect(function()
	if sHLB.Value == true then
		script.Parent.Visible = true
	end
end)

So any ideas?
