Hello,
Thank you for contacting Rank Math support, and sorry for any inconvenience that might have been caused due to that.
I was able to see the duplicate meta tags.
Rank Math should only be generating one title and description tag so there must be another plugin that is generating the duplicate tags. To determine that, kindly follow this guide: https://rankmath.com/kb/check-plugin-conflicts/
Only the site admin would know and your users won’t be affected by this troubleshooting.
Let us know how that goes. Looking forward to helping you.
