I have created a number of parent portals to my main site. However when a navigate to the new alias the URL gets "/en-us/" appended to the end. I notice in the site management tab that this alias as well as "/es-es/" has been automatically added. Although this isn't exactly a big issue to have these extra alias' it is an issue when it defaults to "/en-us/". There's no option to remove them. I have mapping mode defaulted to Canonical and auto add site alias unchecked.

Is there any way to remove this feature or just default to the alias I provided?

Thanks.
