I have also tried just reimporting all the tags, but the artist info gets appended to the title with a hyphen instead of populating the artist field correctly. Is there are a way to do this?
Reimporting from where? With what method?
If you have artist and title in the title tag, use the Guess Values action to split them:
Action: Guess Values
Source Format: %title%
Guessing Pattern: %artist% - %title%
If you are reimporting from another web source, you can do a similar if you click on Utils > Compilation... at the "Adjust tag information" dialog.
