PDF export in the "Note" style leaves a gray halo around the text, while "Essay" and "Academic" export cleanly.

When exporting to PDF, the process is fast and completes without errors, but with the "Note" style the exported text is surrounded by a gray halo/box. On a white page this creates an unpleasant contrast that makes the document look unpolished.

Since the other two styles work well, the "Note" style could be aligned with how they handle the export. The gray background or shading in the "Note" style is probably being carried into the PDF and should be removed or made transparent during export.
