Podcasts not showing up on clip.

When dragging and dropping podcasts (MP3) to the “Podcast” folder on the clip using Explorer, Explorer shows that the files are on the clip.  When disconnecting, however, the Clip itself fails to see any media on the device.  I have tried to move the files to various Folders (Music, Audiobooks) and occasionaly, one of the Podcasts will show up (always the same one but intermittent). 

I have updated the Firmware and verfied that the tags have artist, album and title information.  I have also verified that the Genre in each is set to “Podcast” 

Any ideas what I need to do to get this to work?  Any help would be appreciated.

oh wow.  I know I just posted this but it seems that I have managed to “fix” the issue by changing each of the genre tags to “Other”.  All three are now showing up.

I tried formating as well.  First under settings on the clip and then using Windows Explorer.  Neither worked.  It seems odd to me that something as small as a Genre tag would prevent an MP3 from showing up, but that seems to be the case.
