Wordpress - Custom post type - Taxonomy page - order posts alphabetically

Can someone help me with this on Custom post type page everything is working fine with alphabeticall sort of posts by title:

But when I click on category it s not working fine: This is not working on taxonomy page but it s working in custom post type page where are all posts: But need in categories of custom post type to sort alphabetically

Look at this peace of code in file: taxonomy-opg_categories.php <?php $args = array( 'post_type' => 'opg', 'orderby'=>'title', 'order'=>'ASC' ); $query = new WP_Query( $args ); ?>

Look at in full code on file:

taxonomy-opg_categories.php

<?php $h = new provide_Helper(); $h->provide_header(); $opt = $h->provide_opt(); $h->provide_headerTop(get_the_ID()); $column = $h->provide_column( get_the_ID() ); $theme = $h->provide_set($opt, 'optCategoryTheme'); $blog = new provide_blog(); ?> <section> <div class="block less-space"> <div class="container"> <div class="row"> <div class="<?php echo esc_attr($column) ?>"> <div class=""> <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?> <?php endwhile; endif; ?>

<?php $args = array( 'post_type' => 'opg', 'orderby'=>'title', 'order'=>'ASC' ); $query = new WP_Query( $args ); ?>
