Backup first. This below worked for me, good luck, let me know if this helps!
To reset the (corrupt) System settings do like this:
(Note: All your system settings will be erased - but not your rigs!!)
Switch the main knob to off
wait a few seconds
hold the 'System' key
while still holding the 'System' key - switch KPA to tuner
Ill try this how did you do this system reset so I can try and get rid of this issue
