Hello,

Please once confirm if you have set any specific Header for the Product page or not: https://xtemos.com/docs-topic/how-to-set-different-header-for-specific-page/

Because if you have set the specific Header for the Product pages, then the Overlap wouldn’t appear on that.

If that is not the case on your Site, then please share your Site WP-ADMIN Login details in the Private Content field so that we can check this concern on your Site and help you out accordingly.

Best Regards.
