Why isn't the Sold Out badge displaying in Dawn theme?

Store Design

Hi, I am trying to put the “Sold Out” badges back onto all of my products. The code is not there and I am unsure of how to revert it to the original. Please help! I am using Dawn Theme.

Should looks something like this.

{% if product.inventory_management and product.inventory_quantity == 0 %}

<div class="sold-out-badge">Sold Out</div>

{% endif %}
