podcast space greater than saved podcasts

iPhone 8. In "iPhone storage" for Podcasts it says "Documents & Data 7.48 GB".

But scrolling down shows just 11 episodes (the same as I see inside the app) and a total "All Episodes 339 MB".

Why do I have 339 MB of episodes but 7.48 GB of Documents & Data?

They are not old podcasts that got downloaded again like was happening a while back. I really only have the 11 that I can see.

Thank you.
