Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
Are you using any builder on your site?
Please ensure you add a subheading which contains your focus keyword. Here is a screencast for reference: https://i.rankmath.com/AGZfqq
If you have already added this, please share the affected URL and the focus keyword in the sensitive section so we can look into this.
Looking forward to helping you. Thank you.
