Thank you for your response. I tried your advice and many variations of it with no luck unfortunately:
Based on my numerous unsuccessful attempts, I am at a complete loss as to why these 2 pages are proving to be so problematic. The only remaining culprit I can think of is Skalp; which we are using in our SU model, and whether or not that is affecting the pdf export. However, other pages have Skalp sections incorporated into their scenes and they are exporting fine.
