Teleporting part problem!

[pasje1312]

So this script is supposed to only teleport the backpacks with an owner value to the part with the same owner value and the owner value == to a players name but when the backpacks teleport the right backpacks go to the right ones but the ones without an owner value also teleport for some reason can someone please help me with this?

task.wait(5)
local players = game.Players:GetChildren()
local parts = game:WaitForChild("Workspace").HouseMap.BackpacksQuest.BackpackParts:GetChildren()

for i,player in pairs(players) do
	local randomPart = table.remove(parts, math.random(#parts))
	randomPart.Owner.Value = player.Name
end

local backpacks = game:WaitForChild("Workspace").HouseMap.BackpacksQuest.Backpacks:GetChildren()

for i,player in pairs(players) do
	local randomBackpack = table.remove(backpacks, math.random(#backpacks))
	randomBackpack.Owner.Value = player.Name
end

game.ReplicatedStorage.Values.StoryValues.GetBackpacks:GetPropertyChangedSignal("Value"):Connect(function()
	print("triggered")
	for _,part in pairs(game:WaitForChild("Workspace").HouseMap.BackpacksQuest.BackpackParts:GetChildren()) do
		if part.Owner.Value then
			local partPos = part.CFrame
			local partName = part.Owner.Value
			for _,backpack in pairs(game.Workspace.HouseMap.BackpacksQuest.Backpacks:GetChildren()) do
				if backpack.Owner.Value == partName then 
					backpack.CFrame = partPos
					print("PartOwner is "..part.Owner.Value.."and BackpackOwner is "..backpack.Owner.Value)
				end
			end
		end
	end
end)
