Predictive Text Email Problem

Hi guys, thanks for taking the time to at least read this far, this has been driving me nuts.

I'm having a problem with predictive text. I'm sure it's a dumb one that people far smarter than me can figure out quickly, but I just don't get it, at all.

If my address book has the names David Smith, and Richard Smidgens, if I type in the characters "Sm", it behaves properly, seemingly, and shows both names, as options.

The problem is that it's actually populated the field with the first two letters of the first name it's found.

If I type in a third letter "i", instead of it keeping both name (Smith/Smidgens), it actually adds the i, to the first two letters of the first name, giving me "Dai", and removing the two names from contention for predictability.

Any idea what I'm doing wrong here? Here's the code for this section
Any help would be greatly appreciated...
