Ubuntu :: Edited MP3 Tags - Audio Properties Showing Old Values

I have been editing MP3 tags with Easytag and it has worked for nearly all files but I have some files that when I open them with Easytag, gtkpod Manager, or MusicBrainz Picard, they display the new tags. But when I open these files with Rhythmbox player and when I look at the file properties I see the original pre-editing tags. I know I can change the artist, album, etc. in Rhythmbox player but that just seems to be a local change and I was more concerned by the audio properties of the file showing the old value because I don't want to have to go back and edit the tags again.
