Dead Eye Stance Bugged?

Ok, so lv4 Dead Eye Stance suppose to give you 20% increase in attack power while the other 2 stances gives only 10%. But I noticed when switching to Dead Eye from the other stances I see no increase in attack power when its suppose to give 10% more. Is this bugged or intended?

BTW I'm a Yul Ghost Sentinel.

Thanks

After a lot of mail with NC they said its misstype.

85 1 For 30 minutes, increase P. Atk. +5% and skill power +5% when bow/crossbow is equipped
90 2 For 30 minutes, increase P. Atk. +6% and skill power +6% when bow/crossbow is equipped
95 3 For 30 minutes, increase P. Atk. +7% and skill power +7% when bow/crossbow is equipped
99 4 For 30 minutes, increase P. Atk. +10% and skill power +10% when bow/crossbow is equipped

Those are the real statistics.
