Hello,
I apologize for the issue you’re facing with redirection in small languages. To redirect “ht.natural-field.com” to “natural-field.com”, you can add the source URL as “ht.natural-field.com” in the Source URL field.
Please make sure to select the appropriate Match Type based on your requirement. In this case, you can use the “Exact” match type.
Here’s an example of how it should look:

If you’re still experiencing difficulties, please provide more details about the error or any error messages you’re encountering. This will help us assist you further.
Thank you for your patience, and we’ll do our best to resolve this issue for you.

Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for the delay and for any inconvenience this issue may have caused you.
Please note that Rank Math redirections cannot be used to redirect the homepage/domain or subdomain.
In this case, you may need to use the .htaccess rewrite rule or some other redirection plugin if you want to redirect such URLs. Here is a guide that can help with .htaccess redirects:

Alternatively, you can get in touch with your web host to help you set up those kind of redirections.
Hope that helps.
Thank you.
