I am getting incorrect measurements from nPM1300 fuel guage.

My battery right now is on 3.78 volts and nPM1300 fuel guage showing 3.1 to 3.2 volts and i'm face issues mentioned below :- 

1. voltage not going above 3.3v.

2. current is showing in negative.

3. SoC is also negative at first and then becomes positive gradually.

4. TTF is remaining constant.
