Exclude fields from printing in Twig
You would have to remove the two fields from fields.

&lt;div class="foo"&gt;
  {{ fields.field_events_date_start.content }}
  {{ fields.field_events_date_start_1.content }}
&lt;/div&gt;

{% for field in fields|without('field_events_date_start',  field_events_date_start_1') %}
  ...
{% endfor %}
