This is the so-called indefinite conjugation. The direct object of the verb is indefinite ("ones"), not specific. There are different conjugations for definite and indefinite direct objects. In the name of the Hungarian language, I apologize for this. But once you master this challenge, you will hopefully find it a very cool feature indeed.
