Hi,
Thank you for the details, it helps a lot!
When I try the same search, I am not getting that output: https://i.imgur.com/tjcmRlM.png
You may have had those results cached from a previous pricing (?), but I am not sure. The prices are directly requested from WooCommerce, the plugin does not change anything in regards for the price.
I recommend trying the following variable for the advanced title/content fields instead of using the regular/sale versions:
{_price_html}
..or simply the:
{_price}
By default WooCoomerce should include the sale and the regular prices for these fields automatically.
