Revolution counters not updated

Hi all,

I have been working with IRB 14000 YuMi and recently I have been getting the error 'Revolution counters not updated' from the FlexPendant. The problem is that when I call the calibration routine, the joints can be calibrated just fine, and the 'Calibration' section also shows both arms calibrated. However, once I power off the robot and restart, 'Revolution counters not updated' shows up again.

One thing that I found might be related to the problem is that Axis Calibration seems to be not properly stored in memory. As shown in the image:

However, after checking options on FlexPendant for days, I still haven't figure out how to have the Calibration results stored. Has anyone experienced this error before? Any help is appreciated! Thanks in advance.
