Language filtering on the Hub does not work correctly

[saattrupdan]

(I noticed recently that you changed the language filtering GET parameter from filter to language, but unfortunately my problem still persists)

If I search for Danish models then models like this also pop up, which is not a Danish model, but has the da tag (for "direct assessment"). This could be fixed be filtering by the tag-green class rather than a general tag filtering, as I guess is done currently.

Thanks!
