 * Hello [@dimail](https://wordpress.org/support/users/dimail/),
    Thank you for 
   contacting support. Our plugin doesn’t add Schema markup in the microdata format
   so that error must be coming from a different plugin or your theme. All the Schema
   markup from our plugin is in the JSON+LD format added in a single entry near 
   the top of the page. Don’t hesitate to get in touch if you have any other questions.
