Fan speed reading error

There seems to be a bug regarding the fan speed reading.
Sometimes it happened for the first GPU, sometimes for the last one, regardless the manufacturer (Nvidia/AMD), Does anybody have such an issue?
The fan control is static for exact value or even dynamic based upon temperature, doesn’t matter.
You can check such a behavior for the first fan below. The fan is working ok, i have checked several times:

The only way to correct this is the complete shutdown and reboot.
