I have created a custom post type in my wordpress. The problem is that if I have two diffrent posts in two diffrent categories but with same title e.g. TITLE one of them is TITLE-2 instead just TITLE when my permalinks are configured as %category%/TITLE. I also noticed that if I have post in CATEGORY1/TITLE1 I can just put in a browser CATEGORY2/TITLE1 and I will see this post in two categories, when I put him only in CATEGORY1. How can I solve this problem?

There is my code in function.php

function create_post_type_html5()

 register_taxonomy_for_object_type('category', 'html5-blank'); // Register Taxonomies for Category
 register_taxonomy_for_object_type('post_tag', 'html5-blank');
 register_post_type('html5-blank', // Register Custom Post Type
 array(
 'labels' => array(
 'name' => __('Turnieje', 'html5blank'), // Rename these to suit
 'singular_name' => __('Turnieje', 'html5blank'),
 'add_new' => __('Dodaj nowy', 'html5blank'),
 'add_new_item' => __('Dodaj nowy turniej', 'html5blank'),
 'edit' => __('Edytuj', 'html5blank'),
 'edit_item' => __('Edytuj turniej', 'html5blank'),
 'new_item' => __('Dodaj nowy turniej', 'html5blank'),
 'view' => __('Zobacz turniej', 'html5blank'),
 'view_item' => __('Zobacz turniej', 'html5blank'),
 'search_items' => __('Wyszukaj turniej', 'html5blank'),
 'not_found' => __('Nie znaleziono żadnego turnieju', 'html5blank'),
 'not_found_in_trash' => __('Nie znaleziono żadnego turnieju w koszu', 'html5blank')
 ),
 'public' => true,
 'hierarchical' => false, // Allows your posts to behave like Hierarchy Pages
 'has_archive' => false,
 'rewrite' => array('slug' => 't/%category%', 'with_front' => false),
 'supports' => array(
 'title',
 'editor',
 'excerpt',
 'thumbnail'
 ), // Go to Dashboard Custom HTML5 Blank post for supports
 'can_export' => true, // Allows export in Tools > Export
 'taxonomies' => array(
 'post_tag',
 'category'
 ) // Add Category and Post Tags support
 ));


add_filter('post_type_link', 'projectcategory_permalink_structure', 10, 4);
function projectcategory_permalink_structure($post_link, $post, $leavename, $sample) 
 if (false !== strpos($post_link, '%category%')) 
 $category_type_term = get_the_terms($post->ID, 'category');
 if (!empty($category_type_term))
 $post_link = str_replace('%category%', array_pop($category_type_term)->
 slug, $post_link);
 else
 $post_link = str_replace('%category%', 'uncategorized', $post_link);
 
 return $post_link;
