MC uses Vorbis comments for tagging in the files. I do not believe Name is a standard tag. Vobis/ID3 uses Title for the track name and MC maps Title in the file to Name in its database.
To check what MC is seeing, click on tag and go to the bottom of the listing to Tag Dump. Those are the tags that MC sees in the file.
You might try mp3tag to see if it sees both Name and Title.
Where are you seeing Name in the file tags - Explorer? How did the Name field get defined and entered? It may be just a Windows thing.
EDIT: It looks from your screen shot that the tracks may be wav files, which also may be a problem, since typically wav files do not support tagging, although it is possible to do so, but it is not standard.
