Suggestions for the DaVinci theme

I'm using the DaVinci theme because I like it very much. So, I wanted to see if it's compliant to Google's requirements in terms of SEO, and it failed the structured data test for the pages where a list of products is displayed. Fortunately it's very easy to correct this.

The file in question is products/product.php and all that needs to be changed is this code near the end of file:

<div class="price" itemprop="offers" itemscope>
into this:

<div class="price" itemprop="offers" itemscope itemtype="">
I'm currently using a child theme with a copy of just the faulty and corrected template file.
