problems with RSS feed

hi
i have problems with my feed.
even though i have 2 episodes (and i also published the second one twice), the feed shows only one (and all other platforms such as Spotify and iTunes show one as well)
any idea what went wrong? my reading is set to 10 posts, and i do see the second episode in the episode list.
