Hello,
01. Please Navigate to Theme Settings > Products Archive > Product Styles and check the option “Show Product Category”. There is no option in theme settings to show only the primary category.
02. If you want to hide the all the tabs, Please add this code to the Theme Settings > Custom CSS > Global:
.product-tabs-wrapper{
display:none;
}
This code would remove the tabs from all the products and if you want to hide the custom tabs remove the tab from here, Then Navigate to Theme Settings > Single Product > Tabs > Remove the Additional tabs.
Best Regards.
