Dear Rob,
Thank you for the quick response!
I started with the standard publisher file of a new pretext project and modified the following:
- tableofcontents level="2" in the <common> tag
- visibility of exercise components in the <common> tag
- page geometry in the <latex> tag
- which elements are knowled in the <html> tag
With the exception of the first item, nothing strikes me as being related to the numbering. If the first item is related to this issue in some way, then the print build with latex is still handling the numbering correctly.
I have a separate publication file that handles a different print version where several solutions/proofs are replaced by blank space. The numbering appears correctly in this one too.
I have made no changes within the <numbering> tag in either publication file.
I'm happy to provide more details as needed.
