Default [Q] Nexus 7 2013 LTE issue

Got a N7 2013 LTE with 4.4 RC2 on it.
When I turn on my device the data network is correctly set on 4G; if I change to 2G, 3G, 2G/3G by cycling through from Quickmenu, LTE doesn't show anymore. Going to Settings to choose 4G as default works, but 4G doesn't actually come back. Only rebooting fixes this.
Anyone else with this issue?
