Seeking some technical help with a TP-8120. I made a simple programming change in my channel lineup, and now the radio channel selector is acting strange. Channel 16 in every zone is my scan group, and yet it acts as if it is channel 15 in the channel 16 position and when I click back to channel one, it is still showing channel 2. It’s like it’s missing every other channel unless I use the arrow keys on the keyboard.
I uploaded the most current, firmware and programmed in different code plugs, and returned to the original code plug I was trying to modify and all code plugs acted this way.
Any thoughts? 
Thanks in advance.
