Ranger with bounty hunter background character creation question?

[Vipersfang]

Still new to the game. One of my players created a ranger with the bounty hunter back ground. Both give him Surval ( I think.im at work so can't check ) and normally when a skill doubles up it let's you pick a new one. The rules don't say that in this case. I checked the errata. I couldn't see it. But pathbuilder says you do. Which is correct?

If your class would make you trained in a skill you’re already trained in (typically due to your background), you can select another skill to become trained in.
