There seem to be some courses that do not fit into any of the categories listed in the Category filter. I don't know if these are another unlisted category or if the course is not properly tagged with one of the categories.
One example is "Introduction to the Gospel of Matthew." This is a series of notes on a Bible book. I don't think it fits into the Devotional category. Book Reading Plan does not seem the right category for a Bible book, although that category is used for sections of the Bible such as the Prophets and Introduction to Genesis.
Perhaps there should be a category for study notes or reading guides on a Bible book that would be separate from a reading guide on a book such as Grudem's Systematic Theology. Perhaps it could be called "Bible Book Study Notes". "Bible Reading Plan" would be consistent with "Book Reading Plan", but I know Logos already has reading plans for the Bible.
