@webawen,
The schema markup of your FAQ page is automatically outputted by our plugin when you use the Yoast FAQ block in the default WordPress editor (aka Gutenberg). See screenshot. You can find more information about the Yoast FAQ block on this post: https://yoast.com/how-to-build-an-faq-page/
However, since you’re adding your FAQs using Elementor accordion widget, the specific schema markup for FAQs is not generated. To fix the structured data errors in Google Search Console, you may try any of the following:
1. Compose the FAQ page in the default editor instead of using Elementor accordion so that you can use the Yoast FAQ block
2. Use the Yoast schema API described in this document to extend the schema markup outputted by our plugin. Please note that providing custom code to interact with the Yoast Schema API is out of the scope of our support
3. Don’t select ‘FAQ page’ as the Page type in the Schema tab of the Yoast meta box and use the default value instead
Thank you.
