Go to Admin > Curriculum and expand the T&T Base Club node (or filter the Base Club to show only Truth & Training). Examine the data in the column named "Counts for Accum Award". Make sure all of the non-entrance booklet 'core' books have a checkmark indicating that completing this book does count toward the cumulative book awards (Alpha, Excellence, Challenge, Timothy, etc).
If you see that one of your Ultimate Adventure or Ultimate Challenge books are NOT checked, open that handbook and check the box you'll see on the main page of the generic handbook screen. [Even if the book is obsolete, the box can still be checked so the awards are calculated correctly even for old books.]
[Note: in the Windows App, the Curriculum tab is under Admin > System Settings.]
