Podcasts are not updating in iTunes

Hello,

My website is https://www.aprilshowersmovie.com and my feed, I think, is https://www.aprilshowersmovie.com/?feed=podcast.

I am using WordPress to do my blogging.

Basically I am confused at what is happening here. My podcasts are still being submitted to subscribers and show up here https://feeds2.feedburner.com/AprilShowersMovie when I post my podcasts, but for some reason, if I do a search from the main iTunes store for April Showers Movie, and click on it, not all the podcasts are there. It stops at episode 7, which it was about right after that when I installed feedburner and episodes 8 and 9 have not been showing up. Can someone please help?

Thank you
