How do I delete podcast icons in the Downloaded tab?

How do i delete podcast icons from the 'Downloaded' tab in my Iphone Podcast app?

I sometimes try out new podcasts, listen to an episode, but decide it's not for me. I then unsave and delete the episode, but the icon for the show itself remains in the 'Downloaded' tab of the app and reads below it "1 Episode." If I tap on the icon, it will display "Loading..." for a few seconds but then do nothing else. I did not subscribe to any of these podcasts, but the icons remain there. How do I delete them?
