https://help.libreoffice.org/24.2/en-US/text/shared/guide/pdf_params.html This page starts with examples. All the examples use draw_pdf_Export and an ODG file. And this seems to make people imagine that this draw_pdf_Export should be used everywhere. The last example of this is here: https://ask.libreoffice.org/t/101408/4 ; see also https://ask.libreoffice.org/t/73774/4 and https://ask.libreoffice.org/t/88142. The suggestion is to also use Writer's and Calc's filters in the second and third examples, with an ODT and ODS, respectively - to give the correct idea to the reader.
