Passages are related to the game menu iirc. Passages numbers (in the scene) match the menu-option ID. If you insert a new menu-option in the middle then you break the IDs, you always need to add them to the bottom or rearrange it for all accordingly. I have no deeper knowledge about it, others might be able to help you better at it.
P.S. #2 was more a hint to mark your other thread as solved if you have there no problems anymore
