Diffuse AOV incorrect in Layered Material with Bump

[Njen]

When a bump map is used in the base material of a Layered Material, the first layer of the Layered Material produces incorrect results in the Diffuse AOV.

In the example below, I would expect to only see green and pink checkered squares, no black on the box.

Is this related to my previous bug about the Layered Material (https://forum.corona-renderer.com/index.php?topic=16983.0)?

corona 1.6.2 maybe in daily build something changed

Are you sure you are looking at the 'CShading_SourceColor' render element with the selection set to 'Diffuse'? Because if you are, then your render is also incorrect, but for what might be different reasons. Because I see different shades of green/pink on the different sides of the box, and it should all be one flat colour with no shading.

I can confirm this in 22.08 1.7 daily build. Easy to reproduce by looking at the material editor in Njen's post.
