Django模板变量渲染异常：前39个正常，后续变量不显示

我在开发TAPP.GE网站时，使用Django从数据库中获取网站文本内容，遇到了一个奇怪的问题：模板中前39个变量可以正常显示，但第40个及之后的所有变量均无法在网站上渲染。

上方的文本（如“get endless possibilities”等）与其他变量类型完全一致，但下方带有4个不同图标的变量无法显示。

正常工作的模板代码 #

<div class="col-sm-4">
    <div class="appie-fun-fact-item">
        <h4 class="title">{{ video_bg_stat_3.content_eng }}</h4>
        <span>{{ video_bg_stat_title_3.content_eng }}</span>
    </div>
</div>

无法工作的模板代码 #

即使传递和上述相同类型的变量，以下代码也无法渲染内容：

<div class="row justify-content-center">
    <div class="col-lg-6">
        <div class="appie-section-title text-center">
            <h3 class="appie-title">{{ advantages_title.content.geo }}</h3>
            <p>{{ advantages_subtitle.content.geo }}</p>
        </div>
    </div>
</div>

简言之，前39个变量显示正常，之后的所有变量都无法显示。

视图函数（views.py）代码 #

    context = {
        'in_month': Text.objects.get(name="in_month"),
