Your itunes:summary tag contains a warning that you have strong language, but your 'itunes:explicit' tag is set to 'no'. You need to set it to 'yes' for the overall podcast and for any episode containing strong or sexual language.
Minor points: you don't have an 'itunes:subtitle' tag for your episode, so iTunes shows the 'description' tag which contains a link to an image - iTunes displays the code, which looks messy.
You don't have an itunes:duration tag containing the duration of the episode in the format h:mm:ss. Neither of these is fatal, it's just untidy without them.
When you resubmit it you may be told it has already been submitted - this is a bug in the submissions process - and to get round that you would need to change the title slightly.
