Troubleshooting PDF Exports from FigJam to Dovetail

I'm trying to move some content from FigJam to Dovetail. I keep trying to make pdfs for Dovetail to summarize, but I keep getting the message that there is no content to summarize. I've tried breaking the board up into smaller units and downloading other file types. I've done this before with Miro, but this is the first time I've tried it with FigJam. Why can't I get a good pdf for DT to read?
