Dupilcate Book ID's Found

[James w murray]

can someone explain this new feature in the build song data base part of the program
after i downloaded the new version of hoster i ran the build song database command and got the window saying ther were 5 duplicate book id's
i don't understand this because i searched for a couple of these files it had listed and they are in the hoster song folder as a kma file but there is no duplicate of the file there is just the one file. Before i ran the build song database i could play these files and they were listed now the kma file is still in the folder but it will not rebuild it into the database how do i fix this do i have to re-import the kma file again even though it is already there since it is saying it has a duplicate book ID?
