Default [Q] lte is gone now

Lte was working fine, switching between 3and 4g as I drove throughout the day. Now no longer connects to lte and will not fallback to 3g. I have to turn lte off and 3g will work. I'm a root noob. I have cdma+lte/evdo auto as selected mode.

Any help at all is greatly appreciated.
