Hi antonymv111200,
Thanks for reaching to us.
First of all, I’m really sorry have taken long time to reply you due to the weekend.
1. There are 3 default tabs of WooCommerce:
+ The Additional Information Tab: Shows when the Attributes are added under a Product. If the Attributes are not added then the Additional Information tab doesn’t show.
+ Description Tab: This is the main description on the product page.
+ Reviews: Used to show customers’s reviews.
2. About brand
and Shipping delivery
are custom tabs and can be edited via Theme Settings > Single product > Tabs: https://prnt.sc/bDOK7HP_6t7M, and About brand
itself is enabled here – https://prnt.sc/lZIjdVnv0rS- but the info comes from the description of the Brand – https://prnt.sc/mMqzE–4q2B8
Kind Regards
