[Question] regarding Enhanced Variant Shoes

[Shourei]

Just want to point out a weird bug of mine and a question about Enhanced Variant Shoes

        bonus bMaxHPrate,12;
        bonus bMaxSPrate,12;
        bonus bDef,getrefine();
        bonus bMdef,getrefine();
    ">
},

 
Despite having the above item_db.conf, I can't refine the item.
But if I duplicate the item, I can refine it just fine.
 
Could anybody please tell me what might be the cause?
