Sorry to hear about the inconvenience. Kindly, 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.
The issue was related to the container width settings in your single product layout, which caused the Recently Viewed Products section to overlap the border.
I’ve created a new section inside a new container and added the product module there. It’s now displaying correctly and aligned within the layout.
Please check back your site and check the issue. If you have any questions, feel free to contact us.
