Hello,
Please make sure that you have connected to the correct Google Account, and also make sure the Universal Analytics property is set up correctly.
You can follow this guide:
https://rankmath.com/kb/using-ga4/
Once done, reconnect and reconfigure the settings.
If the issue persists, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.
Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:
https://wordpress.org/plugins/temporary-login-without-password/
You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.
