"Personal Effects" quest bugged

[SirEdeonX]

I'm having a problem on this quest. You need to:

1. gather 5 items from yetis
2. deliver them to an NPC in Falcon's Nest

However, the quest tracker tells me to gather 10 of them.


After I gather 5 however:

it changes to the delivery part:


but the NPC won't take the items I have. I can see the 5 items on my inventory, but the delivery window doesn't pop up.
Tried abandoning it and relogging, but it didn't work.

Sucks cuz it's a chain quest :<
