Storm Haven

The item name is bugged, but that's not why I'm posting, however it may or may not directly relate to my issue.

The item is listed as Forgotten Mithrl Two-Handed Sword, and it has no sell price, however the Staff and the Short Sword that also drop off the Frogloks in Broodlands, where all three items come from, both have 14-1600pp prices. I was just wondering if this was a bug, or intentional for some odd reason. Thanks! =)
