BookID Problem and Zip Files

[xxyzz]

I also cannot get Chartbuster Essential 450 Volume 1 to import. The folder is named:
Essential 450

Inside that folder is a Volume 1 folder. Inside that is 30 folders labeled:
CBE01 THRU CBE30. Each folder contains 15 songs in this format:
Cbe01-01 - Williams, Hank - Lovesick Blues
Cbe01-02 - King, Pee Wee - Tennessee Waltz, The

When I import the first folder using the format DISCID-TRACK-ARTIST-TITLE, the songs show up as they should but the Brand does not show up. If I manually select the manufacturer then the discid gets greyed out. Also the discid number should show up as CBE1-01 but it shows up as CBE01
