Adonis free theme, WoCommerce, Envira Gallery and pages layout

Hi ALl, I've setup my own Wordpress site with Adonis free theme and have successfully configured and installed Envira Gallery and WoCommerce. Now, I've an issue with the product details pages layout on the site: all pages show a Description header and detail section that I cannot edit anywhere. All new products I create are linked to Envira Gallery and automatically create a new website page with url: mysite/product/product-name In these pages the Description header / detail section appears and I could not find any way to edit it. Can you please help. Thanks, Luigi
