ASUS EC OPT Temperatur reading Problem (Maximus V Formular)

I have a Problem with the ASUS EC OPT 1-3 Temp reading:

If no Probe ist plugged in it reads -1.0 °C

If I plug in the Probe while HWiNFO is active it reads 0.0 °C

When I restart the Programm or PC while the Probe is plugged in the Entry is completely gone 
and disappears in Layout Settings.

If I pull the Probe and restart it reappears again.

The BIOS reads correct.

No AiSuite installed.

Debug File attached.

Thank You.
