Episode info appearing incorrectly on iPhone pod app

[Out of the Canon]

I have submitted a podcast successfully and it works on itunes and sync etc, but when it is accessed via the podcast app on an iPhone and subscribed to for the first time there, the episode info doesn't appear, just the start of my email address does (which only appears in my blog's email notification settings, nowhere else). Why/how is itunes pulling this off my Wordpress site to use as the episode information for ALL the episodes that come through?

I did a temporary fix by changing that email address to the name of the podcast, so it doesn't look rubbish, but why don't the episode titles appear as they do on itunes on a computer?
