Greetings,
In the app.logos.com interface, I open Library, and then go through the list of publishers (for the Store books), by pressing the "More »" button.
I've noticed that some of the publishers are not shown this way.
For example, "Saint Paul Seminary Press".
Even if I type the first letter "S" into the Filter box, it is still not shown:

One has to type the first two letters, i.e. "Sa" in order to "reveal" this publisher:

The publishers are ordered by the number of books, and alphabetically within a group with the same number of books.
This particular publisher has 8 books, as you can see from the second screenshot.
But on the first screenshot (with the "S" filter) you can see all publishers with 8 books, but "Saint Paul Seminary Press" is not present.
This is not the only example, there are many of them.
Could you please check why some of the publishers are "hidden"?
