Problem with weapon edit itemcache

[tossuz]

what went wrong here http://img522.imageshack.us/img522/6707/staffzcy3.jpg ? I was trying to change nathrezim mindblade to vengeful gladiators battle staff. And the offhand shows too with the staff now, anyway to make it go away?<.<

You can't change a 1her into a 2her and have the offhand not show.
