Q: Older Episode not showing in iTunes store but is showing to subscribers

I have a podcast that;s hosted on SoundCloud. The RSS feed is located at:

http://feeds.soundcloud.com/users/soundcloud:users:218122065/sounds.rss

Episode: "5 - Top 3 SEO ranking factors for hotels" was published on May 16th.

It shows in the list if you are subscribed (I've read where that list is pulling real-time).

However, if I go to the iTunes store, this episode is not showing:

https://itunes.apple.com/us/podcast/fuel-hotel-marketing-podcast/id1101978909

I've read where this can be a delay with newer episodes, but this one has been published for almost a month and other episodes have been published after this one that show up fine.

I don't want to delete the episode and re-add it because that would delete my listener count and also mess up the order of the episodes.

Is there a way to refresh the list to get this episode to show? Or do I need to change something specific on this episode?
