JBD tools not detecting any current

Hi! I'm having a problem using the JBD tools software with a JBD BMS. Perhaps someone has faced this problem.

The software shows the voltage of my cells and the static balance function works ok, but it seems that it doesn't detect any current through while I'm charging my cells (It shows current =0). So the balancing function while charging doesn't activate. Any ideas of why the software shows current=0 even if a current is indeed flowing through the BMS and my cells are charging? I'm attaching a screenshot of the software. At that moment the cells are been charged with 300mA but it doesn't show that

Does the BMS have a shunt built into it? Or does it use an external one? Is the charging current wired to go thru the shunt?
