Issues changing the tag colour in layout


I’m trying to change the tag colour in Layout - I’ve created the tag in SU and can see it in the drop down list under Sketchup Model > Tags in Layout. I click on the line to the right of the tag name and it changes on this menu. I re-render the model but nothing changes - I’m using ‘Shaded with Textures’ as the Style.

Any tips pls?

The lines beyond the Tag are how edges are displayed, faces are ignored.
You don’t have to ‘re-render’, when you change the line, it should update immediately.
Maybe, the changes are to subtle to notice because the line width is too small.
Share the model ao someone can take a look.
