Hello,
Thanks for contacting us and sorry for the inconvenience caused.
Can you please confirm if you are using the Hello Elementor theme? If yes, the second description tag must be coming from them as they have started generating a meta description from the post/page excerpt.
They have a hook that you can use to disable their meta description: https://developers.elementor.com/docs/hello-elementor-theme/hello_elementor_add_description_meta_tag/
Here is how to add the hook to your site: https://rankmath.com/kb/wordpress-hooks-actions-filters/
If you are not using Hello Elementor, then please follow this guide to figure out which plugin is adding the second description tag: https://rankmath.com/kb/check-plugin-conflicts/
Let us know how that goes. Looking forward to helping you.
Jaideep, you are awesome!!! Problem solved. Thank you for everything.
