4-20ma to 0-3.3v Conversion

I am trying to convert 4-20 mA current loop signal to 0-3.3/0-3 V output for my 10 bit ADC IC that is connected to a Raspberry pi 3B+.

Schematic:

The input sensor is a 12 V loop powered 4-20 mA output humidity sensor. The op-amp is an MCP6002 rail to rail. The output of the op-amp is connected to a 10 bit ADC-MCP3008 (SPI enabled connected to RPi.)

The output voltage only varies from 0.6 to 2 V and I don't know where exactly the voltage drops.

The circuit works fine if I read the voltage using only a 150 Ω resistor (0-3 V.)

I can't understand what's wrong in this circuit.
