BQ34Z100: BQ34Z100 FCC change conditions

Part Number: BQ34Z100

I am using the BQ34Z100 for my battery pack. After completing a full charge–discharge learning cycle, the Update Status becomes 0x06, SOC is 100%, and the FCC has learned the expected nominal capacity.

However, after doing a small discharge, when the voltage drops slightly, the FCC gets reset/changed unexpectedly. I would like to ask what could be causing this behavior.
