PVMT Background Color Problem

Hello, I’m having a very weird problem.

I’m applying (safety) properties to a physical diagram, which should modify the background color. Another employee made several of the “Node PC” blocks different colors to make it easier to see what was what.

I’ve enabled Diagram Styler and done the Choose Properties thing, but when I click the “Reset Style Properties to Default Values” button MOST of the Node PC boxes turn solid black. A couple simply reset and the safety color is applied. This happens even if I restart Capella and the computer. It’s only 5 or so Node PCs that are showing this behavior in the entire diagram; the others do what they should do. And some of a color will go black but not others.

Thanks

Could you share your model or a small example to reproduce the issue?
