Trouble renaming assets

This has already happened to me numerous times, and it is very annoying! Whenever I make a material or blueprint, then rename it, it works fine. However, if I try to return the old name, it tells me that another asset already exists there. Even though there is nothing there. This has also happened to folders, and really any kind of asset. Is this supposed to happen? Is there a workaround? Any feedback on this would be greatly appreciated!

(right click folder in content folder and fix up redirection)
