[Canadaoer] Importing Epubs into Pressbooks

Hey OER list, I'm hoping for some advice, although I think it's likely that the answer to my question is that there's something weird going on in the conversion process that only the folks with access to the source files can fix. I've been working with a group on campus who has created cookbooks in PDF and fixed layout epub format, and they would like to get the books into Pressbooks. They hired a designer for the pdf and epub on a contract, and that person is no longer working with them. The source files they have are nicely laid out with lots of pictures. We can import the epub into Pressbooks, but whenever we do it gets super junky (example<https://books.lib.uoguelph.ca/plantbasedproteins/chapter/plant-based_easy_peasy_cookbook_2021_en_web_for_epub-31/>), while the pdf looks like this<https://guelphfamilyhealthstudy.com/wp-content/uploads/2021/11/Plan… (page 31). It's definitely possible it could be the fault of Pressbooks, but I also took a look at the epub files and when I open them in Digital Editions they also have issues, though the issues are mostly to do with fonts, and are not visible in Books on a mac. Does anyone have any advice for troubleshooting / still getting this content into Pressbooks, or is it a bit of a lost cause?
