Bron says to bring a Creeping grohl and edgy warg!

For some reason, the quest objects show me to :

1) Slay thickest warg[12] at (right bank of shadan) - i see here only the edgy warg lvl 21! (then i do receive an item called thickest warg)
2) Slay Stalking Grohl[21] (the item i receive sm hw happens to be a stalking grohl though)

Translation issues? typo issues?
