By default your custom post types display the post type in the main page header/title because the post title is displayed on the post itself so this prevents duplicate title issues. If you want to display the post title in the main page header/title do so with the following snippet added to your child theme's functions.php file.
function myprefix_alter_page_header_title( $title ) {
if ( is_singular( 'YOUR_POST_TYPE_NAME' ) ) {
return get_the_title();
}
return $title;
}
add_filter( 'wpex_title', 'myprefix_alter_page_header_title', 40 );
