excludeFromXMLSitemap for multilang site

[alkachur]

When I have to language site
and for one Language i need to index page and send it to sitemap but for second language I have no content and try to exclude it via blueprint excludeFromXMLSitemap it isn't works. It works when I select exclude option only for two languages together and not works if one lang is exclude and second include page.

Is any solution for this?
