Default AOSP/CM APN Switching Issues

Has anyone been experiencing issues with the APN auto switching between 3g/LTE? For the past month or so every cm based or aosp rom I try has issues automatically going in and out of 3g and LTE areas unless I manually go into APN settings and switch it. Very annoying while traveling and last week there was the whole "roaming indicator off" message for service instead of "SPRINT". Any solutions or ROMs anyone know of that don't have this issue?

Edit: I'm using CM11 jflte on Philz recovery with the NAE modem. Maybe more success with MK2?
