Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
This feature should redirect you to post listing page and display a list of posts that possess the keyword in question. I have just tested this on my local test site and it works as expected.
Could you please check if one of your installed plugins is modifying this query by performing these steps:
