I think it is due to some tracks having same id (did u use toolkit file of one as a base for another one?) the solution is to repack them starting with new toolkit project evry time
for the lyrics you can use ultrastar creator, upload the ogg file named guitar (in eof) paste the lyrics and synch them to the song (easy to do with ultrastar), then in eof position yourself in the vocals track and edit/import lyrics. if you did good in ultratsar, nothing else to do
good job. I think this list can be useful for downloaders but ultimately I agree with firekorn, to get this list to slim best way is to leave a post in the song thread
