Hello,
Thank you for reaching out with your query. Unfortunately, the theme settings do not provide an option to automatically reorder the product tabs based on their content availability. The behavior you are experiencing is due to the default hierarchy settings applied to the tabs.
To achieve the desired functionality, you might need to consider custom development or use a plugin that offers conditional logic for rearranging tabs based on their existence or content.
Please let us know if there’s anything else we can assist you with.
Regards
