Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. We are sorry for any inconvenience this issue may have caused you.
It is grayed out because you are connecting with the sc:domain.com. Please note that you may need to choose the property https://domain.com/ and not the sc:domain.com upon connecting your site.
The URL-prefix property also helps keep your sitemap in sync with Google Search Console as we submit it automatically for you. In addition, the domain property won’t work correctly on some sections of the Analytics module such as the IndexStatus.
In this case, please follow our guide here to create the URL Prefix property

Then reconnect your site on your WordPress dashboard > Rank Math > General Settings > Analytics.
Hope that helps.
Thank you.
