7.9 created playlist from every album folder

Hi-

Just installed 7.9 on a new server. Install went fine, but under my "playlists" menu item there is a playlist created from every album folder in my collection - One for each album.
Never seen this before. Why did it do this? Is there a settting for this?
Is there a way to globally delete these playlists or to rescan without these playlists being created?

I'm using Windows 8.1 64 bit.
