BUG: TOC behaves differently in 2.3.8

Using the Bible app version 2.3.8 (build 77) to read a book (not a Bible), the Table of Contents behaves in a confusing way.

If I load a book, go to the Table of Contents, and click on a section under a chapter heading, I see "Loading..." briefly. I expect it to take me to that section of the book, but it continues to show the TOC.

If I then press Back a few times (to collapses the sections of the TOC), when I finally exit the TOC, I find that it has taken me to the section I asked for. But that's different to the behavior of previous versions, i.e. I did not have to press the Back button repeatedly to exit the TOC.

Is this change by design?

EXAMPLE: Say I'm reading Charles' Pseudepigrapha of the OT. I press the top of the page, and press the TOC (at the right). I choose Contents rather than verse, and scroll down to The Sibyline Oracles. I press the right arrow (to right) to expand it. Then I press the right-arrow beside The Sibyline Oracles to expand that. Then I click the right-arrow beside Fragments to expand that. Then I press 2. Nothing appears to happen. I have to press the Back button four times before I am taken to Fragment 2 of the Sibyline Oracles.
