Hello,
1. Have you sorted out? Because I don’t see problem with copyrights http://prntscr.com/d9y7f1
2. Previous version had the bug with product category description, that’s why you did not see it. In version 3.0 bug was fixed. If you don’t need category description go to Products > Categories > edit category and remove description.
3. Go to Appearance > Themes > install and activate official WooCommerce theme Storefront and check if you have the same problem with creation of your products. Let me know if problem persists with our theme only.
Regards
