Default No 3G or 4G Data arrow indicator activity...

My L720 with stock rooted 4.2.2 no longer shows any data activity indication (up & down arrows.)
All data connections work, just no activity arrows "light up." (Inactive "unlit" arrows and 3G or 4G symbol do show.)
I have rooted and removed bloat + add hotspot mod and just now flashed the latest CWM recovery to wipe dalvik and cache partitions... no help. That is about all.

Any ideas anyone?
