conflict in taxonomy image fields - php

Question

i use this code to create custom taxonomy with image.
when i duplicate code and change "writer" to any other as "car".
it work but with error in image field.
so i can not now choose an image for both taxonomies.
add_action( 'init', 'create_writers_nonhierarchical_taxonomy', 0 );
function create_writers_nonhierarchical_taxonomy() {
// Labels part for the GUI
$labels = array(
'name' => _x( 'Writers', 'taxonomy general name' ),
'singular_name' => _x( 'Writer', 'taxonomy singular name' ),
'search_items' => __( 'Search Writers' ),
'popular_items' => __( 'Popular Writers' ),
'all_items' => __( 'All Writers' ),
'parent_item' => null,
'parent_item_colon' => null,
'edit_item' => __( 'Edit Writer' ),
'update_item' => __( 'Update Writer' ),
'add_new_item' => __( 'Add New Writer' ),
'new_item_name' => __( 'New Writer Name' ),
'separate_items_with_commas' => __( 'Separate writers with commas' ),
'add_or_remove_items' => __( 'Add or remove writers' ),
'choose_from_most_used' => __( 'Choose from the most used writers' ),
'menu_name' => __( 'Writers' ),
);
// Now register the non-hierarchical taxonomy like tag

'hierarchical' => false,
