Hello,
Thank you for your query and we are so sorry about the trouble this must have caused.
Please head over to the affected post’s editor and check if the FAQ block (if you are using that) or the FAQ schema is still there. See the screenshot below for reference:

If the schema or block is there, please share the affected URL here so we can take a closer look at it. You may share the URL in the sensitive data section.
Looking forward to helping you.
Hi,
Thank you for your reply.
I can see that the affected pages are using the Article schema markup. The problem is that if I add the RankMath FAQ block in the editor, it won’t be reflected to the backend. So the FAQ appear but without the markup. I will add the affected URL in the sensitive data section.
Thanks a lot in advance,
Andrea
Hello,
The FAQ Schema is nested under the Article Schema of your site and that’s why it won’t be displayed separately in the Schema Validator. Please refer to the screenshot in the sensitive data section.
If you want to see the FAQ Schema separately then you can check your URLs with Google’s Rich Results Test.
Hope that helps and please don’t hesitate to let us know if you have any other questions.

Thank you.
