Apple Podcasts Documents & Data is at 10.5 GBs?!

As shown in the photo below, the Apple Podcast app (been seeing this with a lot of apps actually) has a huge amount of data being taken up by by ‘documents and data’. I’ve seen forum posts asking about this, who also clearly state that the actual downloaded podcasts don’t equate to the overall data being sucked up.

Hence why I’ve attached the photo, since the typical ‘fix’ is to just delete already played downloaded episodes. But as seen here, there is a 9 GB difference that’s clearly not being shown. So what it happening and how can I reclaim some of the data? The iPhone and Apple products already take away way too much storage as is with the “system data” that can’t be uncached.
