Boolean fields not showing icons True/False in admin

[Yatchman1]

Hi guys,

the issue is that boolean felds are not showing icons if True or False. All other icons within interface are showing well and even if I "turn off" Jet to display default Django admin, the icons are showing normally.

Any idea?

{% extends "admin/includes/fieldset.html" %}

{% block field %}
    <div class="field-box">
        <div class="field-box__label">{{ field.label }}</div>
        <div class="field-box__value">
            {% if field.value %}
                <span class="icon icon-yes"></span>
            {% else %}
                <span class="icon icon-no"></span>
            {% endif %}
            {{ field.contents }}
        </div>
    </div>
{% endblock %}
