Nomadic Halfling errata? Why gain only one language from Multilingual Feat?

[Pathfinder Way]

So, the Nomadic Halfling heritage grants two bonus languages. Then it says: "Every time you take the Multilingual feat, you gain another [i.e. one] new language."

But the Multilingual Feat says: "You learn two new languages [...] "You can select this feat multiple times. Each time, you learn additional [two] languages."

The Nomadic Halfling heritage seems to be saying that if you have the Nomadic Halfling heritage, you only get one language when you take the Multilingual feat. Which seems to be the opposite of the intent!

Or does it mean to say:
"Every time you take the Multilingual feat, you gain a bonus language due to your heritage, in addition to the two languages you gain from the feat."

[Fuzzy-Wuzzy]

It's that last one.

[Quandary]

Yup, it's not taking anything away from Multilingual's normal functioning, it's just giving additional effect. I don't think there's anything wrong with the wording, it doesn't say "you gain 1 language instead of normal benefit". Same would apply if it said "Every time you take Multilingual you gain 5 hp." you would still be gaining normal effect of Multilingual AND the 5 hp. Saying "in addition to" is not necessary, saying "instead of normal benefit" is necessary if there is a change to base Feat effect.
