so im making a blocking system for my game https://www.roblox.com/games/7188556443/Troublesome-Parkour that makes you smaller whenever you press f but once you release it your supposed to go back to your normal size but for some reason it makes you smaller

local ServerStorage = game:GetService("ServerStorage")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local BlockStop = ReplicatedStorage.RemoteEvents.BlockStop
local BlockStart = ReplicatedStorage.RemoteEvents.BlockStart
local BlockingList = ServerStorage.PlayerList.Blocking

BlockStart.OnServerEvent:Connect(function(player)
	wait(0.05)
	print("fired")

	local String = Instance.new("StringValue")
	String.Name = player.Name
	String.Parent = BlockingList
	
	for i,v in pairs(player.Character:GetChildren()) do
		if v:IsA("Part") then
			if v.Name ~= "HumanoidRootPart" then
				v.Size = Vector3.new(v.Size.X * 0.95,v.Size.Y * 0.95,v.Size.Z * 0.95)
				print(v.Size.X)
			end
		end
	end
end)

BlockStop.OnServerEvent:Connect(function(player)
	if BlockingList:FindFirstChild(player.Name) then
		BlockingList[player.Name]:Destroy()
	end
	
	for i,v in pairs(player.Character:GetChildren()) do
		if v:IsA("Part") then
			if v.Name ~= "HumanoidRootPart" then
				v.Size = Vector3.new(v.Size.X / 0.95,v.Size.Y / 0.95,v.Size.Z / 0.95)
				print(v.Size.X)
			end
		end
	end
end)
