A macro is missing from a PDF

When you export a page to PDF, Confluence asks each app for content it can export. If a macro does not offer any, it is simply left out of the PDF.

Several Formatting macros are in exactly that position.

#What to do

Check the export support matrix. If the macro is listed as not exported, the PDF is behaving correctly.
Publish to a Capable Site instead. Coverage there is much better and links keep working.
Or add a plain Confluence equivalent alongside the macro, so the PDF still carries the content.

The standalone app exports fewer macros than the suite. It exports four, where the suite exports seven. If you are following documentation that says a macro exports and it does not, check which product you are on.

#A few things worth knowing

Here is the difference in practice, with two macros as they appear in a PDF export.

Color palette macro in a PDF export, a table of Primary, Secondary and Tertiary swatches with their hex codes — The Color palette macro comes through an export intact, swatches and hex codes included.

LaTeX macro in a PDF export, showing the raw equation source in a code block instead of the rendered equation — The LaTeX macro does not. The PDF shows the equation source rather than the finished equation.

An image missing from an export is usually a different problem: an external image the export could not fetch.
Site export is richer than PDF export and behaves differently for some settings.
Exporting never changes the page itself.

Check the matrix. It is probably expected.
