Cell standby draining battery eventhough airplane mode is enabled why is it still running?

[Blackdynomite655]

I have a Kyocera Icon KitKat 4.4.2 rooted from boostmobile no service. So when I have airplane mode enabled I look at battery consumption and cell standby is draining my battery and I was wondering why if airpalbe node disable the cell radio and I was wondering why that happening and if there is a way to stop it thanks in advance.
