unwanted erase in UFM

hi everyone, I'm working on a custom board. There is a Max2 on it and I store the serial number of our device in the UFM. Once, one of our customer power down the device and power up again...

I've used UFM for storage of calibration data in a measurement module design, in other words, the data is accessed internally and only rarely rewritten. I normal operation, write and erased are disabled by an external calibration jumper. As far as I know, no memory failure has been observed with a device yet.
