filters not working

"Exclude the following content types from subdomains" is not working at all. Even selection all type of contents is not working.

reproducing the error:

go to personal home: MYDOMAIN/user and edit. I choose "Choose a subdomain:" as USUARIOX (it also doesn't work leaving the subdomain to be created automatically during registration).

in "admin/settings/subdomain/filters" i select "blog entry", or any other for the test.

go to MYDOMAIN/node/add/blog, create new post and save. The content appears in this url:

http://USUARIOX.MYDOMAIN/blog/test --> error, it should be http://MYDOMAIN/blog/test (without USUARIOX)
