The 1xEV-DO screen always works, but the 1x only screen doesn't. It's a strange thing, but hopefully soon it'll be fixed.
Looking at your 1xEV-DO screens, you have perfect signal. So that could explain the signal bars, but I've had strange anomalies with my signal number hovering on -106 in a good signal area every so often.
The CDMA1X screen won't fully populate, even on my iPhone 5.
