When an internal filepath is exposed as a new URL, this usually occurs because you have a redirect that takes place after the request has been internally rewritten.
It is likely that your rules are in the wrong order.
If you have a .htaccess file in a sub-folder, then the rules inside that file are processed after the rules in the .htaccess file in the root of the site.
If there's a rewrite in the root file and a redirect in the sub-folder file then that will cause the observed problem.
Also, be aware that [R] produces a 302 redirect and that for redirects the RewriteRule target should include the domain name. Every RewriteRule should include the [L] flag unless you know exactly why it should be omitted.
