If a Chapter is not being shown within your deck or presentations navigation it is most likely due to the Chapter being Hidden through the 'Chapter In Navigation' setting.
The 'Chapter In Navigation' setting is found within the Edit Chapter Details settings area, which is also the same settings area used to edit a Chapter Title and Path.
To access the Edit Chapter Details settings area you will need to go to a slide that is located within the chapter that is currently hidden. The easiest way to do this is by using the Slide Navigator view to open a slide within the hidden chapter (you can also navigate to a slide using the previous and next slide arrow navigation).
In the example below "CHAPTER 4" is currently hidden within the navigation.
To make the chapter Visible we are going use the 'Slide Navigator' button in the top right corner to access the Slide Navigator view to quickly navigate to a slide within "CHAPTER 4".
To access a slide within the hidden Chapter we double-click on a slide thumbnail to open the slide.
Once on a slide within the Hidden Chapter we click on the 'Chapter' dropdown and select the 'Edit Chapter Details' option.
Within the Edit Chapter Details popup settings window we click the Chapter In Navigation toggle/switch so that it changes from 'Hidden', to 'Visible'.
We click the 'Save Changes' button to confirm this update.
After saving, we can now see 'CHAPTER 4' is now Visible within the navigation.
