Microstation V8i SS4, I have a shape that shows up only when I print from a pset to PDF

Microstation V8i SS4, I have a shape that shows up only when I print from a pset to PDF. The shape does not exist anywhere that I can find. I have checked construction levels and patterns, turned on all levels in the source file and all references, fit view, elevation......Nothing makes this ghost level show up. Any ideas for me, anyone? Thank you
