Fibaro Smart Implant - Can't disconnect IN 2 from OUT 2

Hi

I use the two inputs as "Contact sensor" and the two Outputs as "Switches" independently.

This works for Channel 1 perfectly, but Channel 2 doesn't get disconnected.
If IN 1 gets input it rurns OUT 2 to ON.

I think there is a proble in the driver.

Settings are as follows:

Has anyone the Implants in use completly independent ?

Where can I find the code for the original driver ?

Thanks for your help.
