Few items in your Logical Table of Contents (NCX) is not visible in certain kindle devices such as tablets, E-ink devices and IOS platforms. This issue is seen because those items are set in Level 2. Please change the label entities from level 2 to level 1, so that all the NCX label entities are visible to customers.

Our most illustrious user, Hitch, told me it's most likely because "Kindle for PC can't display <h3> or deeper"... |
Version 2019.2 of the Amazon Kindle Publishing Guidelines (November 2019) added a new guideline:
Quote:
5.2 NCX Guidelines
...
Important: Kindle devices and applications support two levels of nesting.

So, this is a new requirement and they consider it to be important.
The statement about two level of nesting is not exactly truthful. I took a look at a book published long ago that I know has three levels of NCX TOC (
Legends B005LVO6FS) on various apps and devices running the latest software. Only two levels show on a Kindle Oasis and Kindle for iOS. However, all three levels show using Kindle for PC, Kindle for Android, a Fire tablet, and Kindle Previewer 3.
