This is because you are trying to open them in a parallel pane comprised of biblical texts, which by definition means that they must be capable of being displayed in parallel according to the same referencing system. Those modules are all arranged according to their own corpus', and can only be opened in parallel with their texts, e.g. AF-T > AF Crossrefs. If you are working with a biblical text, you should use Comprehensive Crossrefs; it is arranged in biblical order and will show you references to all works, not just those you listed.
I hope this helps…
