WotLK Is this an usebug ?

[CptZenko]

Hello, i've got a weird issue, i can't use http://wowwiki.wikia.com/wiki/Enchant_Bracer_-_Assault ( +24 ap bracer , ilvl 35 or higher) on my http://db.vanillagaming.org/?item=9428 of the monkey , ilvl35 ( and god damn expensive..) .

Its seem to be really weird because the item has the required level . I can also link someone who have this enchant on the exact same item so i dont see any reason why it wouldnt work for me. http://armory.warmane.com/character/...daeron/profile

Thanks for your help, it cost me a lot of money and there is someone who used it, so i feel a bit screw.
