If you look at the SoC (State of Charge) above the graph you will see it is 0%. Probably the chip set TDA (Terminate Discharge Alarm). When the "Ignore SoC" option is enabled the other parameters like TDA or FD (Fully Discharge) are monitored to stop discharging.

Always put a picture with all parameters read from first tab.

This is not a bug. Topic moved in the right place.

Did you change the date of this battery ?

You can try to perform a calibration cycle with both Ignore SoC option set.

I would charge manually each cell to same voltage, you have significant disbalance between cells

Go to Reset tab and press Clear Errors if chip is still locked, check the fuse if it's blown you have to restore it.

After replacing the cells the chip is still in the lock state. You need to do what @torture recommended you.
