Hello,
there are two different lists, both occur in the backend as well as in the frontend:
One list of books, with a study existing for the book. Example: The filter list in the backend or in the frontend to filter the studies list. Or the landing page. Naturatelly, if you have no study on an apocrypha, these books do not appear on that selection lists.
The other list shows all books of the bible, including the apocryphas. This is needed for new / edit study. Here the apocryphas will occur, if you do not modify the database.
Nevertheless, it seems that there is another problem. Where exactly are missing translations? Which view? Which selection box or list? Are all of the books missing in this view or some books only? Is it the official 7.0.1 you use or a different version? As far as I remember, the 7.0.0 had some problems. Is it Joomla 1.6 or 1.7?
