Filelists question

[jolyjigle]

hello everyone..
i have a small problem with my winamp for android... i wonder if anyone could
help me...
whenever i'm deleting a folder of an album (which is a folder containing mp3's and an m3u. and the album cover jpg) the filelist remains in the winamp "filelists" button.
i have to delete the filelist from there seperately.
if i tap that filelist, it just shows a blank list (no mp3s...obviously since they are deleted)
why is it like this?
it's annoying because i like to plug my phone via usb and delete lots of albums in order to put others, so searching for those blank lists is annoying.
any advise?
thank you
