Hello. I need help. I have a custom page template and i have wp pagenavi and the Default Permalink mode work correctly but the Custom %Postname% doesn`t work. What is the problem?

My Page template content:

	<?php
	 // Get the sub-header from sub-header.php
	 get_template_part( 'sub-header' );
	?>

	<!--BEGIN #container-->

		<?php
		 // Get the sub-header footer from sub-header_footer.php
		 get_template_part( 'sub-header_footer' );

		// If the user as set a number of items per page...
		if( get_post_meta($post->ID, "_page_portfolio_num_items_page", $single = true) != '' ) {
			$items_per_page = get_post_meta($post->ID, "_page_portfolio_num_items_page", $single = true);
		} else { // else don't paginate
			$items_per_page = 9999;
		}

		// The selected categories to show
		$cats = get_post_meta($post->ID, "_page_portfolio-types", $single = true);
		?>

		<!--BEGIN #content-->
		<div id="portfolio">  

        	<div class="portfolio-content"><?php the_content(); ?></div>

        	<?php
			if( $cats == '' ) {
				echo '<div class="portfolio-content"><p>No categories have been selected for this portfolio page. Please login to your WordPress Admin area and set the categories you want to show by editing this page and setting one or more categories in the multi checkbox field "Portfolio Categories".</p></div>';
			} else {
				// If the user hasn't set a number of items per page, then use JavaScript filtering
				if( $items_per_page == 9999 ) :
			?>
                <span class="portfolio-browse"><?php _e( 'browse:', 'unisphere' ); ?></span>

                <ul class="portfolio-filters">
                	<li class="all"><a href="#"><?php _e( 'All', 'unisphere' ); ?></a>
                	<?php
                	// display only the selected portfolio categories
                	$cats_array = explode( ",", $cats );

                    // list selected terms in the portfolio_category taxonomy
