Unable to modify posts_per_page on Education Theme blog page

[dwzemens]

I am running Genesis using a heavily modified Education Theme.  I have set Reading -> Post Per Page to 4.  I also have a custom function in the functions.php file which limits the post per page on the is_front_page() to 4 as follows:

add_action('genesis_before_loop', 'dwz_child_before_loop');
function dwz_child_before_loop () {
global $query_string;
if( is_front_page() ) {
query_posts($query_string . "&cat=5&posts_per_page=4&paged=$paged");
echo("<h4 class='widgettitle'>Recent News from St. Malachy</h4>");
}
}

On my blog page, which I created using the standard "Blog" template feature of the theme, is located here:

http://1955design.com/malachy/articles/

As you can see, there are 5 posts per page displayed on this page.  What I cannot figure out is what is controlling displaying five posts on this page.  I've hunted and hunted and cannot figure it out.  In fact, I even tried to use a custom field on this page of query_args = posts_per_page=4 and that custom field argument has no effect, either.

Any help appreciated!
