Default [Q] APN keeps switching

I've been having a problem across a couple ROMs where my APN settings keep switching from T-Mobile LTE to MetroPCS LTE. Is there any way to lock in T-Mobile LTE? I tried APN Manager but it FC when I try to open it, guessing not working with 4.4.x. Anyone have any ideas?
