The issue could be due to how the slides are formatted or how certain elements are handled during the PDF export. Some slide backgrounds or objects might not be fully recognized, causing the background to turn white. It could also be a problem with the software's rendering during the export process. Try exporting the slides individually or checking the slide background settings like https://capapkcutpro.com to ensure they are consistent across all slides.
