BQ40Z50 qmax passed value is negative and soc stays at 100%

Hi,

     I have connected BQ40Z50EVM and BQ24735EVM. I can see charging and discharging cycles happening but SoC stays at 100% irrespective of charging/discharging state. Also I see Time to full and Time to empty also stays at 65535.

Is there any settings that I need to look at to get proper SoC %?

Thanks
