Likely a Name Edit screen will pop up when a new item is created. As it is now, a duplicate of that weapon is placed in the inventory. It is kept separate, but you makes it hard to distinguish them if the wrong CMS is used, since the differences in stats and/or states and elements is not seen.
It works by actually creating new items in the database. If you mess around and create some new items, then close-reopen the editor, you will see that they have been added to your database.
This kinda of makes it hard for creating extractions for items once they have been enchanted though, since they are no longer in the actual original item, but one with a whole new ID, therefore cannot be defined in the configuration ahead of time.
