L99615C current measuring problem

Hello,
I am having trouble measuring current with the L99615C STEVAL kit and wanted to check if I might be doing something wrong. My jumper settings are as follows: J19, J20, J13, and J14 are shorted, while J15, J16, J17, and J18 are set to position 1-2.
I connected a 22Ω resistor between CH+ and CH-, but when I measure the current, it seems that no current is flowing through the resistor. Is there anything additional that needs to be done, or could there be a mistake in my setup?
I also read that for the HS setup, some jumpers need to be removed, but I assumed this only applies when a charger is present. Since I am using power supplies instead of batteries and do not need to use the MOSFET section, I shorted it instead.
I am attaching a picture of my setup and a wiring diagram for reference.
