Hello, first of all, thanks for your reply. I was expecting to get notified of your answer via email but I did not get an email so this is why I saw the reply late.
The code you provided fixed the layout but did not help to fix the doubled display issue of EAN numbers. I added the link to the same product page link below to describe it more clearly.

NOTE: When I remove the SKU from the product page, the EAN numbers are not displayed doubled, and the issue disappears automatically. This info might help you to figure out what is going on.
Okay, I am going to send this message to you via email too.
