Hi everyone,
Thanks for trying to help on this,
So that screenshot is from the PDF,
I think I may have selected something strange at some point in dimensions, or in the dialogue box that gives options for sending to layout.
It all appears normal in plan view, and in layout view once sent there. But when I PDF the layout, the color fill versions of section views sent to layout appear bolded
I've attached the versions: plan view, layout view, then PDF
