Some devices of one physical device are active, others aren't

I have some Fibaro smoke detectors and sometimes some of them display some weird behaviour:

What I think is weird here is: the device is connected directly to the Z-Wave controller (my Domoticz machine), but it shows the last temperature report was on 2019-02-02. I have set the temperature report interval to 720.

I could understand the "Smoke" or "Heat" switches to have a last seen date that is old, but I would expect the "General" and "Temperature" to be more recent. The self test of the device shows it is not malfunctioning.

Can I fix this other than removing the device from Domoticz and adding it again?
