From what I see in the way your filenames are listed is you have only a dash in between each section of it. You will need to pick the defined field order of Artist, Title, DiscId, track number and then edit the separators to be exactly what you have. The default for Hoster is space dash space between all except between DiskID and track number. If you change the field order to be what you have then it will come out right.
From the examples you have given this is the kind of DiskID that is normally used in Hoster. They do not use things like Foundation. Hoster is setup for a letter code for brand and the number from the disc. Thus SC7505 is Sound Choice 7505.
