Recent Podcast Not Shown in Itunes

I published my 4th podcast on our website back on April 13th but saw that it's not been added to the Itunes store yet. The previous podcasts are there. Not sure if I missed a step to add it to itunes store. I thought once the first podcast was accepted, I need not resubmit it and that it automatically will update the feed after a day or so with the newest podcast listed in itunes. here is the url feed. http://specialneedsinmycity.com/feed/podcast/

here is the link to the published post if this helps,

Please advise.

Thanks.
