Printing White Text Over Mesh

Currently using MicroStation V8i SS3. Using the Geographic Tools in a separate file I imported an image from Google Earth that exists as a mesh element type. This file is then referenced into my sheet file to be shown as a background image, similar to using a rastered image.

The issue I am having is needing to print text as white in color. I have the text color set to 255 (BG) and where this was and still does work when I import a raster image I was previously using, the Google Earth mesh does not allow the text to print white whether I use color 255 or even switch it to 0. The text prints black in both scenarios.

As the raster images I have are outdated and of much poorer quality than the Google Earth image I would prefer to use that.

Is this an issue relating to having to use a Display Style of Smooth for the referenced file as opposed to the "from Parent" setting; the sheet file uses a Wireframe Display Style.

This also only seems to be an issue when I have text set to Color="By Level" and the Level Color is set to 255 in the Level Manager. If I set each item of text to Color=255 then the text prints white as intended.
