How can I add a list of words and use Memrise's definitions?

How can I add a list of words and use Memrise’s definitions? When I add the words manually (one by one) I get the definitions of the words but when I include a list of words from the advanced menu (I forgot the names of the menus but I remembered that there are 2 menus and I used the first one) I don’t get the definitions. Why is that? Please help me I don’t want to include each manually.
