elementor_image with wrong media-link after duplicate

Hi, after duplicating a WP site within multisite which is based on elementor (free version), I have identified that the “elementor-image” element has the new copied media files when displayed within the page – but the media link (which is used to view the picture in the lightbox when clicked) is still the old URL. The interesting thing is that I have tried to search and replace in the database and have not found the old URL anywhere. Any ideas?

<div class=”elementor-image”>
<img width=”300″ height=”300″ src=”https://NEW/files/file_01.jpg&#8221; class=”elementor-animation-grow attachment-medium size-medium” ….

so href is wrong and the old URL, src is correct and the new URL created with the duplicate

The page I need help with: [log in to see the link]
