As the screenshot below shows, the parallel resources menu is missing some collections. On the left is a collection, to be shown in parallel resources, that includes several commentaries, including some on Deuteronomy. On the right is a Deuteronomy parallel resource menu that doesn't show that set, nor several other sets that should also show. What seems to be happening is that parallel resource collections are
only shown in they include the current resource. To me this is
counter-intuitive. They should show if the include the current reference.
