Hey Sandip,
Sorry about that. In all likelihood, this is because it is based on odd/even page numbers, and we are one-off (in which case, perhaps tricking the book layout to add a blank page upfront solves that issue, I dunno, we’ve got to investigate).
The Adobe Reader is probably, by far, the worst way of viewing PDFs… Just another case of the cobbler’s kids being shoeless, I guess. Are you by any chance on Mac, where you can use the built-in Preview app, that has a two-page mode (the non-continuous) one that works for this?
I hope this doesn’t ruin the book too much for you.
Best,
