Why is my SQL query running twice? - php

Question

I am using the Zend Framework 2 and notice my sql queries are running twice when pulling values from the database to use in my Forms. I can see in the developertool that it is running twice (two different run times). It only happens with the form elements (not when I echo query results into a table)
I used the below link as a guide:

Thanks
