Leatherworking quests

Hello,

3 of the 6 leatherworking quests from the Jangdor Swiftstrider do not work for me. I complete Wild Leather Armor, Wild Leather Vest and Wild Leather Shoulders successfully, but the other 3 Wild Leather Leggings, Wild Leather Helmet and Wild Leather Boots I can not complete. The quest log shows them as complete I have the items need it, but when I speak with the NPC I can not push the "continue" button. Please help.

Abandon the quests and retake them.

It worked! Thank you very much.
