Best practice, don't make an entry with the same name as one that already exists. Even if you have to use a descriptor of some sort, it can be temporary and may end up being changed. Make sure to type something in description if there is something different. It will prevent something like this happening in the future.
Also, usually if there is some other entry that needs to be changed before making a new entry, I wait until that is done before making the new one. For someone who has to wait on an edit, you can make a post in Listing Errors saying that x item needs to be changed in some way because you want to make a new entry. Such as, existing entry has just a title but needs a descriptor added, and the entry you want to make doesn't need to have a descriptor.
