Hello,
Thank you very much for choosing our theme and for contacting us.
You provide the link to the home page of our demo and I am not sure what banner you mean.
If you want to show the page title: https://gyazo.com/3d6ba10fed3b5a03cb81de68a3143e24 you need to enable the shop title in the shop page and product category page inherit the settings. The shop page is configured locally in the page settings: https://xtemos.com/docs/woodmart/options-for-pages/ or globally in the Theme Settings > Product Archive > Page title: https://xtemos.com/docs/woodmart/theme-settings-panel/#product_page_title
The product category page may have custom content including a banner inserted in the product category descriptions like this: https://gyazo.com/471545e23857835c7554b70004c1480a If you want to show such a banner, you can find the option to configure that in the product category editing mode. Find our documentation tutorial about this here: https://xtemos.com/docs/woodmart/product-category-menu/
If you have any questions please feel free to contact us.
Best Regards
