Reply To: Displaying the product category in the search results

That is really strange.

Okay, so since you added log-in details, I help you out a bit with a customization. Instead of the sale price, I have added the following to the advanced description field:

<div class='product price'>
{_price}
</div>

..and also, this custom CSS to style the prices a bit:

.product.price {
    color: #333;
    font-weight: bold;
}

.product.price del {
    color: inherit;
    opacity: .5;
    display: inline-block;
    text-decoration: line-through;
    font-weight: normal;
}

Now it should be displayed something like this: https://i.imgur.com/dk07oX3.png
