disregard the labels
What matters is the number, that is the time before the card repeats. Anki works through spaced repetition (increasingly large interval before you see the thing again). If you fail to recall, click the again one. If you recalled, pick one of the other buttons depending on how hard you had to push your memory. Since you are using a premade deck, just click "good" when you see something for the first time. (because anki is designed assuming you aren't learning from it but rather making notes on it)
