Metadata not shown in adobe air

Used mp3tag to batch change cover pic in mp4 files and saved but now metadata for year & genre does not show in Adobe air. If I use VLC for single song, no issues with metadata in mp4. Info is in mp4 original file before using mp3tag and shows properly when opening up in mp3tag but does not Show up in Adobe air, using debugger to view. What could be causing this?

If the metadata is complete in MP3tag, I would try to get Adobe air to update its cache or database or whatever it uses.
