Index, and value from table unexpectedly changed

Index and value swap each other unexpected, I expected i to be the index, and v to be the value, but i sometimes becomes the value and v is the index

for i ,v in pairs (PizzaLineNpcs) do
	print(i)	
	v.Humanoid:MoveTo(PizzaLine.Position + (DistanceBetweenNPC * (i - 1) * 2 )  )
end

	if InUseA then
		repeat
		local npc = npcToRegister(CashierAPath)
		npc:Destroy()
		wait(2)
		until not InUseA

Here is the full code

local function npcMaker()
	local npcChooser = npcs[math.random(1, #npcs)]
	local npc = npcChooser:Clone()

	table.insert(PizzaLineNpcs, npc)
	npc.HumanoidRootPart.CFrame = spawner.CFrame
	npc.Parent = workspace.NPCs
	local humanoid = npc.Humanoid
	--Where NPC move to before reaching the line
	--humanoid:MoveTo(workspace.ConnerPath.Position)
	--humanoid.MoveToFinished:Wait()
	humanoid:MoveTo(workspace.DoorPath.Position)
	humanoid.MoveToFinished:Wait()
	humanoid:MoveTo(PizzaLine.Position+ (DistanceBetweenNPC * (#PizzaLineNpcs - 1) * 2 ) )
end
local function printtable(i,v)
	print("index is " .. tostring(i) .. " and value is " .. tostring(v))
	if	tostring(v) == "Tester" then
		return
	end
	print(table.unpack(v),1,#v)
end

local function npcToRegister(loc)
	local Registernpc = PizzaLineNpcs[1]
	table.remove(PizzaLineNpcs,1)
	table.foreach(PizzaLineNpcs,printtable)
	Registernpc.Humanoid:MoveTo(loc.Position)
	--[[
	local path = PathfindingService:CreatePath()
	path:ComputeAsync(npc.HumanoidRootPart.Position, loc.Position)
	local waypoints = path:GetWaypoints()
	for _, waypoint in pairs(waypoints) do
		npc.Humanoid:MoveTo(waypoint.Position)
		npc.Humanoid.MoveToFinished:Wait()
	end
	--]]
	npcMaker()
	for i ,v in ipairs (PizzaLineNpcs) do
		v.Humanoid:MoveTo(PizzaLine.Position + (DistanceBetweenNPC * (i - 1) * 2 )  )
	end
	return Registernpc
end

for i = 1,4 do
	npcMaker()
end


InUseA.Changed:Connect(function(player)
	if InUseA then
		repeat
		local Registernpc = npcToRegister(CashierAPath)
		Registernpc:Destroy()
		wait(2)
		until not InUseA
	end
end)
