False NetApp current alerts

I'm polling a few NetApp boxes (ONTAP 9.9.1P4)

I get some alerts on over current on one of the shelfs' four current sensors.

The maximum on the sensor in OB is set to 0.585A

But where does this maximum come from?

On this NetApp system I have three identical shelfs with the same type disks, and only one of the shelfs are reporting this.. and the OB sensors maximum is not the same??

When I look into the NetApp with "environmential staus" it also does not report any issues... and there isn't even a min/max values for the current sensors as there is for the fans for example...

So this leads be to believe that OB somehow derives this maximum current value of 0.585 from past measurements?    I have tried to reset the sensor in OB, and it is now showing a blank values...

I may have similar issues on another shelf where it reports the fans running at a too slow speed...

Maybe I just need to reset the sensors and they will find their own min/max values eventually?
