custom post type query not showing up all posts

I'm using a plugin nm-woocommerce-personalized-product-v3.6 to produce a custom product found on this page http://www.lovedforever.org.uk/product/donate-flowers/ I'm using the bellow code with in the render.input.php file.

$tmp = '<select name="donation_in_memory_of" id="donation_charity_home" data-type="select" data-req="on" data-message="Please select charity home to donate" style="width: 100%; padding: 0px;">';

query_posts( array( 'post_type' => 'memorials' ,'orderby' => 'title', 'order' => 'ASC') );

the issue is that it only seems to be producing a list of memorials produced by the admin users and no others
