iPod Touch 5th gen won't play a certain podcast

For whatever reason, I can't get a certain episode of a podcast to play on my iPod touch. I know they both work, as I can play it fine in iTunes. But when I transfer it to my iPod, it won't play, even through iTunes. The thing is, it's only episode that won't play. The podcast has 3 episodes so far, and the first and third both play fine on my iPod. But it won't play the second one. It has the little paper symbol with the crease on the top left corner, even though I'm sure everything synced correctly
