Songs/Albums put directly on to Device don't sync
 

I've sorted out most of my issues with Winamp for Android (biggest being track numbers that include a '/' - ie 1/10 - corrupt the track number field on the device) but I can't fix this one that I now have.

Playlist sync works wonderfully, I can auto sync with no problems at all. Whenever I drag an Album on to my device on the Winamp for PC interface, it copies perfectly fine - no dramas at all. However when I then go to Sync my device at a later date I am shown with the following dialogue box:

Notice, one of the Album songs syncs fine (10 will be deleted, 11 in the Album) because 1 of the songs is in my Playlist that I sync with.

Is this a fixable issue (am I just missing a setting) or does it need to be fixed by you guys?

Thanks!
