BQ76940EVM: sense resistor

Part Number: BQ76940EVM
Other Parts Discussed in Thread: BQ76940

Hi;

I am working on Bq76940 referance design Tıda-00255 and I choose the sense resisitor 1m ohm as the same as on the EVM but there is a strange issue that I met.When the  BATT- pin and GND connected with net_tıe the voltages across the cells are observed  truely but the current wrongly on the interface that BQ769X0 software for example it is 4A but on interface it is 6.9 A ; but on the other hand when BATT- and GND pins are not connected to each other ;the current seems true but this time the voltage measured wrongly by IC especially the first and the last cells.

Thanks.
