You can change the product page template in catalog settings.
Please read this page carefully to fully understand all product page elements.
This section is a product long description. It should appear under the attributes table or in the description tab. Before that, you should see the price, SKU and shipping options (all can be disabled). The attributes also can be disabled.
You can modify the product page and product listing layout by clicking on the admin options links located under the image.
Advanced Theme Integration Mode
Currently, [Show Catalog block] is being used on the main product listing.
If the catalog pages are not displayed correctly within your theme layout you can test a different integration method.
