It is the same exact document I exported into pdf 12 days prior with no issues. NOTHING has been changed other than the background colour & tracking of the paragraph style. And NO, this is NOT an overprint issue, I have read that thread through. And NO, this is NOT a version issue either, the same exact version. I could not get this report through with screenshots attached.

And oh, this is not only a pdf-related issue, it's the same thing with exported jpg.
