Assuming that all 14 songs shown imported are good, then just re-import that disc from 15 on.
When you do a re-import, Hoster should show that first 14 are already imported. If it doesn't then you probably have selected a different disc than you selected before. (some discs are in the bucket DB more than once)
Just select the un-imported tracks (15-17) and click import selected tracks.
Hope this helps.
