BUG report on using Greater Essence

the greater essence are supposed to turn magic in to rare item.
but after i socketed the weapon, it doesn't allow me to put on the essence as it said socket is not empty. I don't know if it was suppose to be this way or not. (which it shouldn't)

Please fix this, or at least if you can take the socketed gems out for me i would really appreciate it cuz the item i traded is quite expensive.

Thank you for your consideration
