Auto-detect rx noise level not working?

Hi all,
I'm preparing a new node and noticed that the radio-tune-menu choice (2), "auto-detect rx noise level" doens't work anymore.

I worked fine on the last nodes I've configured.

I do have a flat output on my TX and no squelch, so the noise is always present.

Has something changed in the last versions ?

The other choices are working and I can tune the node to work properly.

I thought this level was important as it served as a reference for the max audio input level.
