Tool/software:

Hello, the current detection circuit is shown in the above figure, in which the capacitors C19 and C20 are not connected, but the detection current is abnormal when charging. 
The actual input current is 100 mA, the display current is 3824 mA, and the input voltage is normal, which is 12.3V.Is it a software setting problem or a hardware problem ?
