Hello!
Thanks a lot for the bug report. Could you please share the stylesheet used with your document?
Thanks a lot for the bug report. Could you please share the stylesheet used with your document?
The document has no links to stylesheets. Maybe pandoc modifies the file when processes it and adds some stylesheet to it.
Can you reproduce this issue without stylesheet?
Can you reproduce this issue without stylesheet?
No, I can’t.
I’ll try to find in pandoc’s code if it’s using a custom stylesheet.

I don’t find anything here: https://github.com/jgm/pandoc/blob/60974538b25657c9aa37e72cc66ca3957912ddec/src/Text/Pandoc/PDF.hs#L418
Maybe the pandoc team can help you debugging this issue?
@mariohuq Is there anything more we can do for you? Many things have changed in text management with version 53, and without a way to reproduce it’s hard for us to know if it’s fixed.
