Radio 3 "The Essay" errors for recent episodes in podcast page and feed

gistfile1.txt

Radio 3 has a program called "The Essay" with RSS feed (which I mostly use) @

http://downloads.bbc.co.uk/podcasts/radio3/essay/rss.xml

and podcast page @

http://www.bbc.co.uk/podcasts/series/essay

Currently, for episode title=

Venice Unravelled_Episode 5of5_Water Level

, both sources link to

http://downloads.bbc.co.uk/podcasts/radio3/essay/essay_20150127-1054a.mp3

That file is downloadable, and has correct-looking MP3 metadata=

BBC Radio 3 - Essay: Venice Unravelled_Episode 5of5_Water Level

Unfortunately the actual *audio* in that file is plainly from the previous Essay episode,

The Book That Changed Me - Sir Paul Nurse 23 Jan 15

And it gets worse! Just now I checked the podcast page for the URI for the Paul Nurse episode,
thinking someone might have just switched the two. Alas, the URI provided for that episode is

http://downloads.bbc.co.uk/podcasts/radio3/essay/essay_20150123-2300a.mp3

... which is the same URI as that provided for the episode *before that*, titled

The Fall and Rise of the British Castle

Worse yet, the latter episode also (on that webpage) claims to have aired on the same day
as the Nurse episode, which seems obviously wrong.

So, plainly, someone needs to get into the source for the podcast page=

http://www.bbc.co.uk/podcasts/series/essay

and fix a few recent entries--notably, retarget the content links.
Extra credit for fixing the feed as well.
