Alternative answers - how do they work?

Hi everyone! I need some help, recently I started playing translating whole sentences, which I find really helpful with practicing output. Of course sometimes there will be several ways to say one word and unfortunately there are also some mistakes in the sentences, which I reported, but I don’t think will be fixed any time soon - I thought that’s where the alternative answers would be helpful. However, I don’t think I understand how to use them, can someone explain it to me? I tried putting everything in the “alternative answers” field, the whole sentence with new version of the word, as well as only the new word itself, someone suggested to put them between square brackets, but that also doesn’t do anything, Clozemaster still accepts only one answer. Help!

Cheers,

H.
