Not able to discern visibility

[manxomfoe]

I'm trying to use show / hide on layers and groups as the differentiation between my objects on version 40.3 of Sketch and am receiving the report "No layer with distinct style" - Attached is basic image / configuration. I'm working in Examples.sketch and have added an "underbar" group with four individual rectangles.

My expected behavior would be that it could see the "isVisible" on each layer and change only that attribute. The usefulness happens when I can use LayerGroups instead of individual layers and they can each have different children.

Is it possible that Sketch has moved the visibility of the layer into a different method than "isEnabled" and you could use "isVisible" on MSLayer instead? (Sorry, not good enough with Cocoa to figure this out completely)
