Podcast Episodes Disappeared

We've had our podcast published on iTunes for about 6 weeks now. It can be "found" here: Balanced Pursuits by Kristi Leskinen & Jen Hudak on Apple Podcasts.

When I published our 5th episode today, all episodes within our podcast disappeared. However, if you do a generic search for Balanced Pursuits, the search pulled up all 5 individual episodes. Other apps have subsequently picked up the 5th episode and are still displaying the other 4 (pocket cast and cast box).

Any idea why or how this happened?? And furthermore, how we can fix it??

Thank you!
