I know why !
If you have only 3 items, it's because you've activated the "Power saving" mode (not UPSM).
This feature was implemented since v4.3 (I'm on Amcha 4.3 and I have same battery stat "problem").
Try to disable Power Saving in toggles and you'll see complete display of battery stat.
(Sorry for my bad English...)
edit: you are right, i tried you method and yes, appear other process.
the same happen when you reboot the phone on my phone.
the problem is for @Bijuu...he havent complete stats also after reboot.
