This is probably how esword displays all versions with apocrypha. Some books aren't available in Arabic. They just appear in the list to the left.
To show Arabic (and this goes for Hebrew text as well; to enable to read from right to left, I'm not certain how that setting can be done from T4. I'm certain that some one may know how that is done. However, to save waiting for a responce to this, open your arabic bblx file in either SQLite Manager (a Firefox add-on) or SQLite Browser. Then click on the Details table, and in the Right to Left field edit the record to read the numeral, 1. Make certain that the numeral, 0, is deleted.
In the Font field, ensure that it reads as ARABIC. If not, then edit that record to read as such.
I think, hope, believe, and trust that this should work. Let me know how it works out for you.
Blessings,
