Bank of questions : where are the slides ?

Hello everyone

something I don't understand: I got an ST360 file in which a colleague created a question bank (QB). But the only way to see the question slides is through the QB. They do not appear in any scene and yet when I enter the QB, it shows me all the question slides as elements of a second scene

I don't understand why I don't see the scene where the question slides are located directly ?

thank you in advance
