Hello,
Thank you for contacting Rank Math support, and sorry for any inconvenience that might have been caused due to that.
We can’t seem to find any issue on our end. Please refer to the screenshot of our own local WP installation:

The URL you sent needs a username and password for us to view it. Can you please share a screenshot from your end instead? You may use this tool https://imgbb.com/ to upload your screenshot and share the URL here.
For initial troubleshooting, check if there are other plugins or your currently active theme that are causing the issue. To determine that, please refer to 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.
Looking forward to helping you.
