That's because you have added your 'Incomplete' folder as a share folder. Any files with preview or numbers in front as you suggested are incomplete folders. You either ignore this folder unless you want to trial a partial dwnld, or remove it as a shared folder - what do u want? Do you want to share your partial dwnlds? If not, then in your LW Tools-Options & Uploads in the Basic section unclick 'Allow Partial Sharing' & then press Apply. Then of course go back to LW's Lib & press Refresh.
