Thanks for your message and welcome to the PTXprint community!
Sorry to hear that there’s something going wrong with ch1 vs1. Does the same thing happen for other books at ch1 vs1, or is it only happening in James?
You may already be on the right track, that it is happening because of the footnotes/references. But if it was working finr earlier (1.9), then this is a regression which we need to fix. If you click on the Help tab, you will see a button to create an archive. Please send the archive (of just the book of James) to us at [Email Removed]. We will look into it and try to rectify it.
By the way, does it also happen in version 2.1 (which was released over the weekend)?
