When I open the index Chapter in a Book, Indesign opens all the other chapters
I have an Indesign book consisting of several chapters (about 500 pages in total). One of these chapters is the index, a normal document in which I have created interactive buttons that open the other chapters (in the exported interactive Adobe PDF).
The problem only occurs when I open the index chapter, and when I do, all the other chapters open at the same time, sometimes directly in the upper document bar, sometimes in background (I know because a dot appears next to the documents in the Books tab). I then usually try to close all the other documents except the index, but when I click on a button and then open the Buttons/Modules tab, the document linked to the button opens again.
Now, how can I avoid this problem? This is very annoying as my PC freezes and takes forever to open all the documents.
I'm currently using version 20.0.1 x64 on a Windows 11 OS.
