Can not find Slot 2 Pokemon in Friend Safari

I have been looking for a Monferno for 10 minutes now, but i am only encountering the slot 1 Houndour. Am I doing something wrong?

you need to complete the story

2nd slot pokemon(like moneferno) in friend safari require 6 badges and you need to beat the elite four to unlock 3rd slot from 1.2 onwards.

Ah okay, I thought the Slot 3 pokemon would need 6 Badges. Thank you.
