Have you enabled the Enable Extended Kobo Features under the Extended tab in the KoboTouchExtended driver configuration?

Yes, I double checked via the calbire preferences --> change calibre behavior --> advanced --> plugins --> KoboTouchExtended --> Extended --> checkmark on beside Enable Extended Kobo Features

Strangely, the original problem books
did have a toc.ncx that visually looked just like the non-problem books in Sigil. Some problem books did have a cover-image tag, some did not yet many of the working books did not have a specific cover-image tag so it didn't seem like that was the problem.
I used to have various plugins in my older Sigil but at some point I stopped adding them with the Sigil upgrades. I'll look into getting those back.
Sigil without the plugins still definitely did
something to fix the problem but only if I manually edited the existing TOC - which I did via it's edit-the-TOC menu option & only changed the text portion not the link. So something broken got fixed along the way somewhere.
Thank you so much for the all info! I've still got lots to learn.
