All cells voltages shown in 1 cell

Hi. I was working on a battery and I wanted to charge it but suddenly I saw voltage error . When I checked the battery info page I noticed that my battery is shown with strange cells voltage. As if instead of 4 cells I have 1 cell and the value is equal to the sum of all 4 cells! 
I suspected wiring and soldering but everything was fine. I contacted ev2300 and it showed the voltages the same way on the NLBA software.
But when I started the BqEvsw it would show the cells voltages correctly. 

This has happened a few times in the last few weeks . And the problem automatically fades away after a few hours. I think a bug fix is needed !
