I’ve a website. It was initially developed by a different developer. It has custom template work done to it. In the wp-admin “projects” can be seen in the menu.

When I click all projects, all projects appear and can be seen also on the projects page of my website. In the pages a blank page called “projects” is created and the template it is using is “projects template”.

On the projects page of my website I can see all the projects added but when I add a new project (Add its’ title, description, category, featured image) it is not being shown on the projects page.
The code for Projects template is as follows:

 <!-- pakistan projects -->
 <section>
      <div class="container pb-40">
        <div class="section-content">
          <div class="row multi-row-clearfix">

          <?php $args = array( 'post_type' => 'projects', 'posts_per_page' => 70 , 'orderby' => 'meta_value_num', 'order' => 'DESC',
    'meta_key' => 'size' ,'category_name' => 'pakistan');
                      $loop = new WP_Query( $args );

                      if ( $loop->have_posts() ) : while ( $loop->have_posts() ) : $loop->the_post(); 

?>

            <div class="col-sm-6 col-md-4 mb-sm-60 text-left sm-text-center">
              <div class="volunteer maxwidth400 mb-30">

                <div class="overlay">
                  <div class="content text-center">
                    <h4 class="author mb-0"><a href="<?php the_permalink(); ?>" class="text-white"><?php $excerpt = get_the_excerpt();
 echo mb_strimwidth($excerpt, 0, 100, '...');
 ?>
 </a></h4>
                    <h6 class="title text-black font-14 mt-5 mb-15"></h6>

                  </div>

                                ?>
                             <h3 align="center"> 

                                    <?php echo get_post_meta($post->ID, 'project_malysia', true) ; ?>
                            </h3>

Summary:
Can see the newly added project in the project list appearing in “All projects” but not on the Projects page which is using “Projects template”. However all previously added projects which are appearing in the “all projects” are appearing on the website. Any help will be highly appreciated.
