@PatrickM I tested the stroke width selection from the Properties panel on an object with no stroke and it is working here (both on Windows and Mac).
If there is a short recording of what happens when the object is selected and the Properties panel is used for stroke selection, please link it here, it would help replicating the issue. Thanks.
