Our plugin only provides the ability to add tabs. It doesn’t define or change the way the tabs look. We don’t add any HTML or CSS to a site that could change tab layout and style.
The way the tabs look is defined by your theme and WooCommerce itself. You should submit a ticket with your theme developer and they may be able to help you with style and layout.
