Data from duplicated post persists

When I duplicated another Review post and changed all the content, the <script> tag with the JSON data about the product is still the old information from the cloned post. It’s also there when I check the validity on the product in Search Console. I’ve tried to clear the cache and deleted old transients and revisions, but to no effect.

Is there a way to clean or reset the data? Is this a know problem when cloning review posts?

Here’s the script tag which includes data from the old cloned post:
