Hi if you are using Genesis theme, you need to disable the Genesis Schema. Here is Bill Erickson article. https://www.billerickson.net/yoast-schema-with-genesis/
There is not an option to restore the Yoast SEO 10 behavior. If you or your developer return false or an empty array on the wpseo_json_ld_output filter, you disable all Yoast SEO’s schema output.
add_filter( 'wpseo_json_ld_output', '__return_false' );
Typically code snippets are added to your theme’s functions.php file. If you’re not familiar with using code snippets, these articles have wonderful advice:

Thank you for replies.
I can’t be the only person using schema.org info in their theme.
Yoast 10 works perfectly.
I will keep using Yoast 10 until someone adds an option to selectively disable the duplicate info that Yoast 11 adds to my pages.
Maybe you have to remove microdata from your theme. I had same problem and I have used this plugin to have only one schema:
