It's just luck that the SQLite Manager version appears to give the right answers, it quite likely doesn't!

This is a very common problem for SQLite. How do I get the data for the row that has some some max (or min) value in one of its columns?
You have to use INNER JOINS to do it, first work out the max() value for each letter, then use that as a joined table to find the matching row in the main table. Try this:
