Rowena New NM Leves Npc

Hiya, i have some problem with this NPC unless i'm overlooking something.
I did the NM leve and obtained the Allagan Runestone - Oschon wich correspond to "Harlequin's Belt".

I Speak with Rowena using the "Tell me what you have." option, then a list of items pops up, i pick the "Harlequin's Belt" and she says this:

"Rowena: A harlequin's belt, is it? Then this is what I'll need from you─an Allagan runestone - Oschon, 3 circles of peiste leather, 2 circles of storm-blue boar leather."

I have in my inventory the Runestone + 3 peiste leather + 2 circles of storm-blue boar leather, after that dialogue she asks me "Complete the Exchange? yes or no" picking yes will result in this:

"Rowena: I ain't runnin' a charity here. Exchanges are only made when payment is made in full."

And she doesnt give me the item, anyone knows why? am i overlooking something? Or is it bugged?

did you try and trade the npc? or maybe you need gil or you doign somethign wrong ; ;

It's bugged. Quite a few people have been unable to trade the correct items for the belt. You'll just have to hold onto your rune and wait til SE fixes it.
