InDesign 2020 - I have create a multi-chapter book. When I use the function "Esporta libro su PDF…" the file PDF obtained has the summary correct (all the chapters are dysplayed) but bookmarks only appear for two chapthers.
I've tried changing the order of the chapters to see if it's a file problem, but the result doesn't change. The last chapter does not appear in bookmarks list.

I remain at disposal for any clarification
