Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
I have splitted your post to a new thread so you can use also use the Sensitive Data section.
I checked it in a local installation with the last Rank Math version but I was not able to replicate your issue.
Assuming you are using the latest version of all the plugins and the themes (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.
To determine that, please follow this troubleshooting guide:

Please let us know if you find the culprit.
Only the site admin would know and your users won’t be affected by this troubleshooting.
Looking forward to helping you.
Hi Caroline,
Just to make sure, are you using the regex method?
Make sure your settings match these. Make sure to change the domain to your own:

Let us know.
