Media URL Erases after Publishing

Hi there! I’m trying to post my podcast to my website using a direct download link with libsyn, however, the media player won’t show up on my published post.

When I am creating a new post, I enter the direct download link under “Podcast Episode” and verify the link. The link says “Media Verified Successfully” and I click on the “Podcast Episodes” category and click publish.

Here’s where the problem starts, after publishing my post, the page refreshes and the media link I had previously verified erases and therefore, the media will not show up on the updated blog.

How can I publish my post without the page erasing my media url? Thank you for all of your help.
