Why is there a different number of posts on the page all the time?

Question

Django

There is such a cycle. For some reason, Chrome always displays a different number of records. In IE and Opera everything is fine. Clearing the cache doesn't help.

{% for draft in drafts %}
          <div class="item">
            <div class="price-item">
              <a href="{% url 'draft_detail' draft.slug %}" class="upper">
                <div class="slideshow">
                {% thumbnail draft.img "800" crop="center" as image %}
                  <img src="{{ image.url }}" alt="" style="z-index: 1; display: block;" />
                {% endthumbnail %}
                </div>
                <div class="desc_box centered">
                  <div class="label col-md-6 offset-md-3">
                    <p class="name">Расчет № {{ draft.number }}</p>
                    <p class="desc">{{ draft.title }}<br / >
              				{{ draft.get_oven_display }}<br / >
              				{{ draft.furnish }}<br />
              				<span class="yellow">{{ draft.get_full_price|intcomma }} СЂ.</span>
                    </p>
                    <button class="btn btn-transparent btn-full upper white">Подробнее</button>
                  </div>
                </div>
              </a>
            </div>
          </div>
