Hi,
This change that I made was done in the Swift Framework plugin and not in the theme files.
The problem is that was necessary to change a field name and this will cause problems in the existing content of the others customer pages, and it’s not easy and fast at the moment to provide a solution that works 100% for the old shortcode format and for the new one that I created for your site.
I will provide you some code so you can add it to your child theme and have that modified version of the Single Image asset, so you don’t have to worry with the updates.
Later today or in Monday I will provide it to you.
Thanks
-Rui
