InDesign Margin Exporting To PDF


I've been using InDesign for 6 years, and I've never had this issue. When I export a file to a pdf, the margin line is showing up on it. I can't seem to find anything online about this issue and have no idea why this would be happening. I didn't update or change anything with my version of InDesign. It started happening yesterday.

Edit: here's the picture. I had to mark out the identifying info, thus the weird white boxes. You can see the purple line - that's the margin guide that should be invisible when exporting. It doesn't show for any other format, just when I export to PDF.

There is a setting during export:

Visible Guides And Grids

Exports margin guides, ruler guides, column guides, and baseline grids currently visible in the document. Grids and guides export in the same color used in the document.

Examine that setting.
