I just bought "The Johannine Writings" (https://www.logos.com/product/5884/the-johannine-writings ) in the Sheffield Reader Collection series. I was quite surprised, on opening the book, to see that the Table of Contents doesn't seem to have been set up the way they normally are in other books. By this, I mean that you don't get the ">>" at the top of the tile allowing you to expand the table of contents into a sidebar (see below). In addition, I don't get the line at the top of the tile telling me whereabouts in the book I am at any time.

I do have one other edition in this series, and the Table of Contents can be expanded (see below).

Is this right?
