Check which tag version you have written. WE does not understand V2.4, it has to be V2.3.
Also, if you had BAD! tags then you should check your files for integrity with utilities like foobar2000, mp3val and/or mp3diags. Files that are somehow messed up sometimes do not display properly in WE.
Thank you... That helped and I was able to resolve all my issues...
It was a daunting prospect to have to resolve this since I am dealing with a .mp3 catalog of over 10000 files with about 2500 indicating that they had a problem, but the apps you mentioned solved the problem.
