Podcast app is using storage, even though I have no saved podcasts

Hi!

My Podcast app is taking up 1.2gb of storage, even though I have no saved podcasts.

I have manually deleted played episodes and cleared everything in my queue, but the storage won't clear up..

If I enter Settings > General > Usage Storage and open Podcasts, it states that documents and data takes up 1.2gb, but there is no clear button...

How can I free this storage?
