iPad won't sync podcasts marked 'explicit'

I've had tons of trouble syncing podcasts to my iPad2. I thnave 21 appearing in iTunes, and on the iPad as it's listed in iTunes. But on the actual iPad there are only 5 showing. Is it a coincidence that these are the only 5 that are not marked 'explicit?' Is there a setting I can change that will allow the podcasts to sync to my iPad?

I've created both a regular and a smart playlist, plus just allowed the podcasts to sync as normal. It's always seemed pretty random which ones actually show up on the iPad or not. But today I noticed the 'explicit' thing.

Please help! This is driving me crazy not being able to listen to all my podcasts.
