Hoster deletes from Database already imported discs

[rickyrey]

When I used my discs to do a show I always numbered them to avoid putting different names to each disc(for example, some KJs identify Soundchoice disc 1520 as sc-1520 and so on) Well, my problem is that I had imported the discs with numbers to folders that are named the same way and it correspond to the folder I am using. When I import I click next in the import window and to my surprise is not following any order, then I go to My Computer to check what is happening and the Book Id Root has an imported disc already with the exact name as the folder. I update the database every time I import a disc. why Hoster is not recognizing the already imported Book ID?
