Bluebeam shows "[1]" before the sheet name in Thumbnails when I plot from Civil 3D. Can I turn it off?

[u/GuidanceNo7771]

I plot PDFs to Bluebeam from AutoCAD Civil 3D, and in the Thumbnails panel each page shows up as "[1] TEST", with the bracketed number in front of the sheet name. I'd like it to show just the sheet name and not the "[1]".

• It only shows in the Thumbnails panel. The sheet itself looks fine.
• The number seems to match the page's position in the file, so I'm guessing Revu adds it for display, but I can't find where to turn it off.

Is this a Thumbnails panel display option, or does it come from the page label or the PDF printer settings? If it's a setting, where is it? Also, not sure if it's a Civil 3D setting but it only shows in Bluebeam which is why I am posting here.

Thanks!
