Issues with Filtering in Select Single using Collection Template and ADP

Summary

I have a select single using an ADP displaying employee first name, last name and phone but it is not always filtering correctly when typing

I have attached a sample application that has 1 select single.  The select single is using an ADP loaded from the employee business object.  It is also using a collection template to display the employee first name, last name and phone number in the select single.  I pulled the base code from the VBCS cookbook.

I am seeing two (2) issues:

1. If I type the letter O the select single doesn't appear to filter at all.  However, if I type a second O, the select single filters to just 1 row with the last name "Khoo".  The second O is filtering correctly, but not the first one.
