Time Left In Chapter greyed out?

[gers1978]

On many of my sideloaded AZW3 books, the option for "Time Left In Chapter"is greyed out.

Many other books are fine.

In all cases, opening the books in, say, Calibre, reveal they have a ToC, and in fact on my Voyage itself, I can "GoTo" the Table of Contents, and it shows many chapters.

Any ideas?

The normal reason for this is that the book in question does not have chapters (at least not what the Kindle recognises as chapters.)

When I hit GoTo, I see:

Beginning
Page or Location
Cover
Table of Contents
End

When I choose Table of Contents, it takes me to the page in the book with the contents, every chapter is underlined and I can press one of them to take me there.

I suggest trying a different book and see what happens.

Yes, but you're not seeing a list of chapters on the "Goto" page. That indicates that, as far as the Kindle is concerned, the book has no chapters. It doesn't contain a correctly-formatted table of contents.

Look at another book and you'll see that, when you tap the "Goto" button, you see the chapter list.
