Tabs show inside of a theme tab
When you activate the Tabs Studio app embed in a theme, the app will try to find the location of the product description so that it knows where to show the tabs and what content to show in them.
If the product description is inside of a tab that's created by the theme, the tabs from the app will show inside of the tab from the theme.
To show the tabs from the app instead of the tabs from the theme, use the theme settings to deactivate the theme's tabs.
If you're not sure how to use the theme settings to deactivate the theme's tabs, please contact your theme developer.
If the tabs from the app don't show after the theme's tabs are deactivated, try the resolutions in the tabs do not show after being activated article.
