Podcast episode is missing

Hello everybody,
we are hosting our Podcast at our wordpress webseite. We are planing a rebranding and were trying to move the poscast to another domain. This didn′t work yet. But what happend is, that our new Podcast episode doesn′t show up on spotify and co (The old episode are still online and available).
On our website the new show #27 (its online twice because I was trying to upload it again just to check):
Our RSS Feed (https://thehighersisters.com/feed/podcast) is empty. Do you have a solution for us, how we can fix it and all episode show up on spotify, iTunes and co?
Thank you very much!
Sarah
