Hello,

Any tab title is important as it clarifies what content this tab contains. We would recommend writing your title, and we can set the transparent colors to hide. As soon as you set it, please give the page URL.

The Extra content block has several options to be located. You can find the option on the product page: https://xtemos.com/docs-topic/product-page-options/ and https://xtemos.com/docs-topic/product-page-local-settings/

If you have any questions please feel free to contact us.

Best Regards
