Loss of Temperature sendor readings since Cerbo GX update to latest firmware

since I have installed the latest Cerbo GX Firmware update my Temperature sensors have stopped displaying on the screen when I go into the settings all are showing open circuit ? No wiring has been touched since update ! Help please.

I am assuming they are the wired ones?

Go through the settings menu and check if they are stil switched on.
If they are then check if it will show an error if they are unplugged.
