LTC4162-L icharge_jeita_x values keep reseting to default values

I have problem with setting up icharge_jeita_x values. I can set up registers to my custom values, but after short time (milliseconds) they keep rolling back to default values. With other registers I don't have such problem (e.g. LTC4162_CHARGER_CONFIG_BITS_REG with changed en_jeita).
