I've tried it on geonode with the states layer.
I've created a new CSS style for this layer and then I edit it as suggested by @allyoucanmap.

The CSS style name is My style.

The style has been saved without errors, I returned back and saved the changes with the save button. After that the TOC appears like this:

So the layers settings are available but when I try to re-edit the style its name is changed in Solid fill:

Is this acceptable?
