Custom Post Type with Custom Taxonomy Not Working

I have a page using the shortcode that was working fine until I added the custom taxonomy I created. Nothing is displaying.

Here is the shortcode:

[ajax_load_more container_type="div" taxonomy="categories" taxonomy_terms="i-sober-story" taxonomy_operator="IN" category_post_type="i_sober_story" posts_per_page="8" button_label="VIEW MORE" transition_container_classes="grid-x grid-padding-x small-up-1 medium-up-3 large-up-4" scroll="false"]

Here is the custom post type code and taxonomy code:

function ru_custom_post_i_sober_story() {
 
	$labels = array(
		'name' => _x('I Sober Story', 'post type general name'),
		'singular_name' => _x('I Sober Story', 'post type singular name'),
		'add_new' => _x('Add New', 'I Sober Story'),
		'add_new_item' => __('Add New I Sober Story'),
		'edit_item' => __('Edit I Sober Story'),
		'new_item' => __('New I Sober Story'),
		'view_item' => __('View I Sober Story'),
		'search_items' => __('Search I Sober Story'),
		'not_found' =>  __('Nothing found'),
		'not_found_in_trash' => __('Nothing found in Trash'),
		'parent_item_colon' => '',
	);
 
	$args = array(
		'labels' => $labels,
		'public' => true,
		'publicly_queryable' => true,
		'show_ui' => true,
		'query_var' => true,
		'rewrite' => true,
		'capability_type' => 'post',
		'hierarchical' => false,
		'menu_position' => 5,
    'supports' => array('title','thumbnail', 'author'),
		);
 
	register_post_type( 'i_sober_story' , $args );
}

add_action( 'init', 'build_taxonomies_i_sober', 0 );  
function build_taxonomies_i_sober() {  
   $labels = array(
		'name'              => _x( 'Categories', 'taxonomy general name' ),
		'singular_name'     => _x( 'Category', 'taxonomy singular name' ),
		'search_items'      => __( 'Search Categories' ),
		'all_items'         => __( 'All Categories' ),
		'parent_item'       => __( 'Parent Category' ),
		'parent_item_colon' => __( 'Parent Category:' ),
		'edit_item'         => __( 'Edit Category' ),
		'update_item'       => __( 'Update Category' ),
		'add_new_item'      => __( 'Add New Category' ),
		'new_item_name'     => __( 'New Category Name' ),
		'menu_name'         => __( 'Categories' ),
	);

	$args = array(
		'hierarchical'      => true,
		'labels'            => $labels,
		'show_ui'           => true,
		'show_admin_column' => true,
		'query_var'         => true,
		'rewrite'           => array( 'slug' => 'category' ),
	);
	
	register_taxonomy( 'categories', array( 'i_sober_story' ), $args );

}
