Psychic

I'm relatively new player here. So, I'm kind of bummed when I'm the Psychic cuz a bit confused. Its role description says that "Odd nights= AT LEAST ONE would be good" so this means that one of the people in vision is good and the other is evil, right? This is just putting that there's no enchant or SC. But whenever I claim that the other person is evil (eg, (1) is confirmed town that leaves 2 as evil).

Whenever I say that, the other person would say that BOTH of them can be good. And I often get pushed by evils because of this. But going back to the Psy's role description, it's "ATLEAST ONE". I just want confirmation if what I'm understanding is wrong.
