Perhaps I'm missing something, but when I select a file with no tag information, and select "Convert/Filename - Tag", the program says "Tag derived from 1 of 1 files", but the information is not actually copied to the tag. That is, the set of tags to the left (Title, Artist, etc.) do not change.
The format string matches the filename, so I am confused as to why this would be happening. Any clues?
