Help My phone wont connect to the lte network just 4G

[gcaf1]

Hello I have a lg optimus g pro and it wont connect to the lte network. It connects using 4G only. I don't know if the apn settings were changed or if lte can be turned off somehow . Any help would be appreciated. I am on the AT&T network.
