Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
Could you please clear the browser and website cache and try adding the Keywords again?
If that doesn’t work, please try removing the Rank Math Transients. To do so, head over to WP Dashboard > Rank Math > Status & Tools > Database Tools > Remove Rank Math Transients.
Please note that some options are only available in Advanced Mode.
If the issue persists, please go for a conflict test with the help of this guide: https://rankmath.com/kb/check-plugin-conflicts/
We hope that helps. We are here if you need us again.
Thank you
