Hello.  My Uv5R build 291 will not save offset frequency and + or -.   I have read the FAQ showing that if this happens, you have to delete the line and add it again. This does not work.
 
I have even started with a Fresh reset, new IMG file, Added one and only one line manual with chirp.  Programmed radio, memory line shows up in the radio but the - and + are lit up at the same time and there is no offset when I key up. 
 
My friends UV5R with build 297 does the exact same thing.  One line manual or 128, They all read -+ at sametime.  He said he gave up on trying to fix it.
 
Any suggestions? I am sure this has to be something simple I am overlooking. 
 
Thank you for any help you can provide.
