displayLeftColumn does not show up

[miko784]

Hi, I have a problem with the hook. Everything in the panel is configured and added in the code. Unfortunately, the categories are not displayed.

            {block name="left_column"}
              <div id="left-column" class="col-xs-12 col-md-4 col-lg-3">
                {if $page.page_name == 'product'}
                  {hook h='displayLeftColumnProduct'}
                {else}
                  {hook h="displayLeftColumn"}
                {/if}
              </div>
            {/block}
