Woo Framework: woo_cat_featured not populating

Question

So I fixed it by changing

array(
    'taxonomy' => 'category',
    'terms' => array( $woo_options[ 'woo_cat_featured' ] ),
    'field' => 'ID',
    'operator' => 'IN'
),

to

array(
    'taxonomy' => 'category',
    'terms' => array( $woo_options[ 'woo_cat_featured' ] ),
    'field' => 'slug',
    'operator' => 'IN'
),

Specifically:

    'field' => 'ID',

to

    'field' => 'slug',

.

I’m not sure what changed from one theme to the other. But this made it work perfectly.
