It's not a bug, it's a feature :)
You can disable it, or change its setting in the misc. tab
You can also replace the "artists" tab by a "artist" tab with the menu you get when right-clicking on the tabs.
The "artists" field is a special field derived from the "artist" field and also a bit from the "title" field.
