Pixhawk Cube 2.1 with 2 Power Modules Help

Hello all and thank you in advance for any assistance.
I have a hexa with 2 batteries and 2 ProfiCNC PM’s.
Each battery goes to 1 PM that ends to the same PDB and PM1(left) is connected to power1 and PM2 is connected to power2. I have tested and verified that if i disconnect either battery or POWER plug that the system works. I have managed to configure and tune PM1 to give good numbers, but so far i am not able to configure PM2 to give its own numbers.
Does anyone here know if the Volt and Cur Pins are different between P1 and P2 or joined?
