EVAL L9963-MCU measuring unprecisaly

Hello i have problem with evaluation kit. I tried to connect evaluation kit to battery pack model that was made from  13x parallel combination of capacitor 470nF and resistor 1kOhm. I wanted to measure voltage on seperated parallel combinations representing battery. I tried two wiring setups (viz. pictures in attachment). When trying to measure with voltmeter almost every cell is measured precisely by Eval kit. Only last one cell (cell1 or cell2 depending on wiring setup) is always measured with 200mV error. So i wanted to ask if i connected everything right. Thanks for answer in advance.
