@agiudiceandrea, @orcaomar: Finally, I remembered this and found the time to look closer into the matter.
My findings so far:

1. A numeric field cannot have ALL their values equal to NULL (as @agiudiceandrea states in his/her comment).
2. It seems like the maximum number of type numeric and integer fields is four. If I have more then four numeric fields I get the error message.
3. The layer has 23 features. This gets narrowed down to 16 when adding the "Data Range Filter". Why?
4. The slider "floors" the maximum value in the field? A polygon in my data set has the maximum value = 74797,9247. The slider's max. value (on the right side) shows 74797 resulting in the polygon not being visible (included).
5. The layer has four numeric fields. However in the "Filter" I see only: "fid" > 4.000000 AND "fid" < 34.000000 AND "artype" > 12.000000 AND "artype" < 60.000000 AND "areal" > 372.704900 AND "areal" < 74797.924700 Why is not delta_m2 included in the filter? It is included in the legend in the layers panel.
6. Removing the legend widget in a) Layers properties is not enough. One has to also b) clear the Filter. Shouldn't doing a) do the trick alone?

Anyway, I find this legend widget very useful and would really like to se it included in QGIS. Any chances for that?

Four numeric fields:

23 features:

Just what I was looking for.
Downloaded the plugin as a zip-file and installed it from zip in QGIS 3.24.2.
Added a polygon layer and added the the plugin to the legend-property, but it throws an error:

`An error has occurred while executing Python code:

Do you have any plans updating/supporting the plugin? Or have you asked QGIS to include such an option in the core version?
