Hello again,
you can continue using the Paired Top layout when you have more than one image in the listing and it should not be an issue for you.
As for whether or not this will resolve your already active listings, I am unable to say for certain until there is a resolution, but as that code (the HTML for your listing) is already up on eBay, it is unlikely to resolve it for already active listings, but we'll let you know when we have more information available.
Thanks,
Craig
