sidebar in selecting page template not working

How did you set the two columns layout? On which page did you use a page template? Which is that page’s address?

The general layout options applies to the entire site (categories, posts, pages, so on) except individual pages using a different page layout template.

@ZedCryout Thanks for answer…
Im checking on your answer and what I can see is that the page for technlogy blog https://www.gb-advisors.com/es/category/tech-blog/ is rendering by category, which I think is causing the template not loading the sidebar.

In my page attributes I set that page “technology blog” this way:
Parent: About GB
Template: Two columns, sidebar on the right
order: 0

Also my permalink structure shows me: Permalink: https://www.gb-advisors.com/about/technology-blog/ ?

In my menu I see the structure is under Category (Now I know why is showing under the category page) Now the question is how to do the category shows with the sidebar?
Do I need to set page instead of category and create a page-template for query the technology blog?
Better to do that with a child theme?
What will be your recommendation?
Thanks in advanced!

I did get that to work by making a child theme and choosing the template i’ve created as this:
page-blog.php which has a query for my blog categories. So I had assigned the template just for that page…@ZedCryout Thanks a lot, your answer makes me to moved in that direction

Next question is how can I achieve to the single.php shows sidebar.
I want to show all the posts as a blog, I mean with the right sidebar too, but again the problem is what you said above:

The general layout options applies to the entire site (categories, posts, pages, so on) except individual pages using a different page layout template.

I think I can use a filter in my child functions to tell wordpress that dont apply the general layout for the posts template…can you help me with this please?

I answer myself in order to help anyone else trying to achieve that kind of results.

First I’ve created a child theme…change the page which was showing the category for a page template I’ve created
In my case my page template was page-blog.php with this structure:

<?php /*
 * Template Name: Blog dos columnas
 *

 */
get_header(); ?>

		<section id="container" class="two-columns-right">

			<div id="content" role="main">

				<?php get_template_part( 'content/content', 'blog'); ?>

			</div><!-- #content -->
			<?php get_sidebar('right'); ?>
		</section><!-- #container -->

<?php get_footer(); ?>

Then another file under the folder: content.
This file has the query of my category, in my case i named it content-blog.php

<?php
/**
 *
 * Learn more: https://codex.www.ads-software.com/Post_Formats
 *
 * @package Cryout Creations
 * @subpackage Nirvana
 */
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
 $args = array(
    'category_name' =>'tech-blog',
	'order' => DESC,
	'post_per_page' => 6,
	'paged' => $paged
);
query_posts($args);

if ( have_posts()  ) while ( have_posts() ) : the_post(); ?>

				<div id="post-<?php the_ID(); ?>" class="page-blog">
                	<div class="imagen-blog"><?php the_post_thumbnail('blog'); ?></div>
					<?php if ( is_front_page() ) { ?>
						<h2 class="entry-title"><?php the_title(); ?></h2>
					<?php } else { ?>
						<h1 class="entry-title"><?php the_title(); ?></h1>
					<?php } ?>

					<div class="entry-content">

                    <div class="meta">
                    <p><?php the_date(); ?>&nbsp;-&nbsp;  <?php the_author(); ?></p>
                    </div>
                    <div class="clear"></div>

					<div class="separator-blog">	

					<?php the_excerpt(); ?></div>
						<div style="clear:both;"></div>
						<?php wp_link_pages( array( 'before' => '<div class="page-link">' . __( 'Pages:', 'nirvana' ), 'after' => '</div>' ) ); ?>
						<?php edit_post_link( __( 'Edit', 'nirvana' ), '<span class="edit-link"><i class="icon-edit"></i> ', '</span>' ); ?>
					</div><!-- .entry-content -->
				</div><!-- #post-## -->

				<?php  comments_template( '', true );
				endwhile; ?>

				<?php if($nirvana_pagination=="Enable") nirvana_pagination($the_query->max_num_pages); else nirvana_content_nav( 'nav-below' );

			 ?>

And finally to show the single page with the sidebar too what i did was altering my functions.php to this:

add_action('template_include', 'load_single_template');
  function load_single_template($template) {
    $new_template = '';

    // single post template
    if( is_single() ) {
      global $post;

      if( has_term('tech-blog', 'category', $post) ) {
        // use template file single-template-cat-1.php
        $new_template = locate_template(array('single-template-cat-1.php' ));
      }

    }
    return ('' != $new_template) ? $new_template : $template;
  }

And created a file named: single-template-cat-1.php which has the sidebar in it!
Done…working perfect
