Can't select a section within category when creating a section

Hi,

Im trying to create a subsection, but I can only select a category.

We are on the enterprise plan.

This is the code in the template 

{{#if section.description}}
        <p class="page-header-description">{{section.description}}</p>
      {{/if}}
      {{#if section.sections}}
        <ul class="section-list section-list--collapsed {{#if settings.content_layout_columns}}single-column-layout{{/if}}">
          {{#each section.sections}}
            <li class="section-list-item">
              <i class="fas fa-folder"></i>
              <a href="{{url}}">
                <span>{{name}}</span>
              </a>
            </li>
          {{/each}}
        </ul>
      {{/if}}

      {{#if section.articles}}
        <ul class="article-list {{#if settings.content_layout_columns}}single-column-layout{{/if}}">
          {{#each section.articles}}
            <li class="article-list-item {{#if promoted}} article-promoted{{/if}}">
              {{#if promoted}}
                <svg xmlns="http://www.w3.org/2000/svg" width="10" height="10" focusable="false" viewBox="0 0 12 12"
                     class="icon-star" title="{{t 'promoted'}}">
                  <path fill="currentColor"
                        d="M2.88 11.73c-.19 0-.39-.06-.55-.18a.938.938 0 01-.37-1.01l.8-3L.35 5.57a.938.938 0 01-.3-1.03c.12-.37.45-.63.85-.65L4 3.73 5.12.83c.14-.37.49-.61.88-.61s.74.24.88.6L8 3.73l3.11.17a.946.946 0 01.55 1.68L9.24 7.53l.8 3a.95.95 0 01-1.43 1.04L6 9.88l-2.61 1.69c-.16.1-.34.16-.51.16z"/>
                </svg>
              {{/if}}
              <a href="{{url}}" class="article-list-link" title="{{title}}">{{title}}</a>
            </li>
          {{/each}}
        </ul>
      {{else}}
        <a href="{{section.url}}">
          <i class="section-empty"> {{t 'empty'}} </i>
        </a>
      {{/if}}

But when I create a new section I only can select a category, I can't select a section within the category to create a subsection.
