Product rewiew schema inserted twice

Hello,

I using the Otter block plugin to create product review and automatically insert schema.
I also use the Kadence Table of content as block element to fetch heading in content and automatically a add table of content in my posts.
If i check the “Search for Headings in Non static post content” option in the ToC of the Kadence Block plugin, to automatically fetch and add the “Notre avis sur : Galaxy Watch 4” H2 title, the product schema is inserted twice.
Do you know how could i resolve that ?

Thank you
