According to mupdf this pdf file is malformed:

Bad or missing prev pointer in outline tree, repairing
format error: Outline last pointer still bad or missing despite repair
Couldn't load outline for 'C:\Users\kjk\Downloads\David.Freedman_.Robert.Pisani_.Roger.Purves.-.Statistics.pdf'

Hmm in such cases I try different tricks to fix but Acrobat Reader and Pdfium Edge will often reshuffle contents but the bookmarks are still the same even though one file is now bigger and one now smaller!

The best of the Lot is MuPDF-GL and again it sees the bookmarks as working yet offers a fix, but I have to fiddle with settings to ensure it alters to include the bookmarks.

Uploading David.Freedman_.Robert.Pisani_.Roger.Purves.-.Statistics - Copya.pdf…

We can see the signature is now Mupdf compatible too (%µ¶)

According to mupdf this pdf file is malformed:

But, MuPDF-GL (v1.23.0) displays the bookmarks correctly. So, I think that the issue is in SumatraPDF.

(I am not saying that the PDF doesn't have any issues. But, if MuPDF can display it correctly, SumatraPDF should also do the same.)

@GitHubRulesOK, how did you use MuPDF-GL to repair the PDF? I know about mutool clean. Are you talking about that?

It doesn't work in latest mupdf, I opened an issue https://bugs.ghostscript.com/show_bug.cgi?id=707750

No MuPDF viewer is also a format editor you can do many things such as draw annotation with or without incremental save or in this case resave with corrected syntax. similar to command line clean but inside a gui. the flag that there is a problem is a very small asterix in title bar but simple "Save as" did not clear the problem and acrobat or tracker did not grumble either as they could also work within any error tolerance!

@kjk FWIW the poor file worked in 1.20 Mu.PDF-GL (last official 32bit) but agreed NOT my compiled 1.25 which also causes me other issues ?

resave with corrected syntax. similar to command line clean but inside a gui.

Exactly how? I couldn't find any reference online.

Sorry if I am diverging from the main issue too much.

press A bottom right "save as pdf" > deselect incremental and then the cleanup commands should be at the bottom
Save as must be a new name and needs click not enter !!
