It depends on North American English usage versus European; NA uses singular verbs with plural/collective, while Euro often uses plural verbs with collective nouns. Like the Swedes, who study Euro-English, so do the Danes.
Due to dual usage, Duo should at least accept either use in English translation. But we should learn to use plural verbs with collective nouns in Danish, because they apparently do.
