Wordpress: Capabilities Custom Post type delete_po

Question

I'm using Custom Post Type and "Members" plugin in wordpress.

My problem is that in my custom post type I can't delete posts, the link to move to trash is not there :(

Here is my code:

'capabilities' => array(
  'edit_post'          => 'edit_entrada_tallers_activitats_grups', 
  'read_post'          => 'read_entrada_tallers_activitats_grups', 
  'delete_post'        => 'delete_entrada_tallers_activitats_grups', 
  'delete_posts'        => 'delete_entradas_tallers_activitats_grups',
  'delete_others_posts' => 'delete_others_entradas_tallers_activitats_grups',
  'delete_published_posts' => 'delete_published_entradas_tallers_activitats_grups',
  'edit_posts'         => 'edit_entrada_tallers_activitats_grups', 
  'edit_others_posts'  => 'edit_others_entrada_tallers_activitats_grups', 
  'publish_posts'      => 'publish_entrada_tallers_activitats_grups',       
  'read_private_posts' => 'read_private_entrada_tallers_activitats_grups', 
  'create_posts'       => 'edit_create_entrada_tallers_activitats_grups', 

In the Edit Capabilities page plugin it appear and I have checked the checkbox of:

• delete_entradas_tallers_activitats_grups (delete_posts)
• delete_others_entradas_tallers_activitats_grups (delete_others_posts)
• delete_published_entradas_tallers_activitats_grups (delete_published_posts)

But not "delete_entrada_tallers_activitats_grups" ( the delete_post) maybe this is the problem but I don0t know how to fix it....

UPDATE full code

function my_custom_post_tallers_grup() {
  $labels = array(
    'name'               => _x( 'Aquí t’escoltem', 'post type general name' ),
    'singular_name'      => _x( 'Taller i activitat per a grups', 'post type singular name' ),

I have found some error in your code so I rewrite your full code.

Note: You can translate it on your on Language

function tallers_grup_post_type() {

// Set UI labels for Custom Post Type 
    $labels = array(
