EVQ7228-QJ-00A NVM cycles

Hi MPS experts,
We are using EVQ7228 evaluation board.
When we use the evaluation tool of Virtual Bench Pro 4.0, the value of Remaining Write Cycles in NVM may change from NVM=1 to NVM=2.
I don’t think the number of NVM cycles will ever change to 2, so is there a reason why this phenomenon occurs?
