korg Nanokontrol issue

[eranatis]

I was on firmware 1.0.8 and had many issue with korg nanokontrol to control volumes on bluebox .
Problems like freez of all the controls even on the touch screen but the music continous playing on the bluebox and I had to disconnect the nanokontrol to unfreez the volumes controsl on the touch screen . And when I reconnect the nankontrol to the bluebox the mapping was not fluid, not smooth anymore.
I upgraded the firmware to 1.2.7 it's worse : when I push 2 or more fader at the same times the faders on the screen follow by jumping or froze there position.
please help
