So, do i understand it right: You have got a string i.e. in description and title of you persisted SeoMetadata and the description isn't displayed in the meta tag?

[boxbillinggit]

Yes displays only the title, and the rest meta is no longer in the object SeoMetadata the show and the display is already only the title correct.

i just tested this in the cmf sandbox with the latest version of the seo bundle and it works there. do you output all information in your template?

        {{ sonata_seo_metadatas() }}
        {{ sonata_seo_link_canonical() }}
        {{ sonata_seo_lang_alternates() }}
        {{ sonata_seo_title() }}

if you followed the documentation, is it maybe lacking, could we improve something there?
