INA219: INA219 invalid display output

Part Number: INA219

Hello Community,

I'm using the current sensor INA219 with NRF5340dk.
Communication is through i²c protocol and using nrf SDK v1.8.0 .
I'm trying to get the data output (Bus, Current, Power).
i worked on the sample linked on Zephyr Lib.
The problem is:
i connected the sensor to a DC Power Supply i gave it 0.47 in entry but the sensor is blocked on 0.39999 
i think there's a range limit or something like that to configure 
do you have any idea what to do get the right values displayed on the power supply 
i will attach explaining pictures below

i even tried with the voltage the sensor is not indicating the right values that i give through the power supply

ddoes anyone knows what might be causing this please ?

the wiring of the sensor is like below :


and i think there's something to do also with the voltage because it's not indicating the right values displayed on the power supply 
is there a range to play with or a gap of values to change ? 
are you familiar with that please ?

thank you in advance
