Rather than overriding the default, localized resources are being included along with the default.
This means that if you have resources/abc.css and fr.lproj/abc.css, the output CSS will include both CSS files.
It appears that the "filename" for files under the resources folder is "resources/abc.css", while the lproj is just "abc.css"; the "filename" property of the manifest entries probably needs to drop the "resources/" portion.
