BQ78350_R1 Issues

I am using the BQ76940 and BQ78350 on a custom PCB to measure the voltages of 15 series cells. I have successfully programmed the firmware to the fuel gauge, and when I read word '09', it results in 0xB0 (after sending command 08 to target address 0x17). However, I only seem to be reading 44 mV from each cell (I have measured 3.2v across each), and the temperature for some reason is stuck at 196.4 degrees celsius. When i try to calibrate voltages (or anything for that matter) i receive an error stating that the block size returned after command was an incorrect length. I have attached a screenshot of what i am seeing. Any guidance would be appreciated.
