How do you make this nametag script not make nametags overlap?

I tried some ways but i can't figure it out, please help.

local billboardgui = game:GetService("ServerStorage"):WaitForChild("BillboardGui")

game.Players.PlayerAdded:Connect(function(player)
	
	player.CharacterAdded:Connect(function(character)
		local clonedgui = billboardgui:Clone()
		clonedgui.TextLabel.Text = "Player"
		clonedgui.TextLabel.TextColor3 = Color3.fromRGB(36,154,136)
		clonedgui.Parent = game.Workspace:WaitForChild(player.Name).Head
		
		while true do
			wait()
			if player.Name == "ivan6361" then
				local clonedgui = billboardgui:Clone()
				clonedgui.TextLabel.Text = "Owner(coder)"
				clonedgui.TextLabel.TextColor3 = Color3.fromRGB(36,154,136)
				clonedgui.Parent = game.Workspace:WaitForChild(player.Name).Head
			end
		end
	end)
end)
