Exclamation [Q] Accessing 4G LTE with CM nightlies?

Hey XDA community! I am here to just ask if anyone else in 4G LTE rich area for Sprint just cannot seem to pick up LTE. I have a Nexus 5 in the household and it picks up 4G LTE but the EVO does not. I have tried switching my preferred network type to CDMA/LTE as well as changing my APN (access point names) to "Sprint LTE Interet". No luck however any ideas? Do I have to edit any settings in the APN for it to work?

Thanks for the help and time!
