Hi Jelena,
Very odd, and notice as Matt said it is not in all, but certainly quite a few.
As an example, I checked this FAQ note http://service.sap.com/sap/support/notes/821739 that is referenced in the one above, and the numbering is right, but the formatting is off.
I will follow up on this to see if it is a known issue.
You mentioned that you can't save in PDF? Can you see a PDF version button at the top of the note? That should enable you to view and save in PDF.
Thanks,
Kristen
