The Man From Interpol - eposides - deleting a 'phantom' epoisode.

Many moons ago it appears that someone was creating an episode guide for the  'Man From Interpol' television series and could not find the title of episode 7 - so they wrote "no entry" as a place holder.

So, many moons later, we now have an episode in IMDb called 'No Entry' and a series which had 39 episodes made, having 40 listed in the database.

I have double checked on US and UK TV listing - this is not the name of an episode - not even an a.k.a - just a transcription error.

Episode 7 is actually called 'All the Dead Were Harrisons' - and that episode has been sitting outside the numbered listing for a while.

THE PROBLEM IS  - I cannot see a way to delete this phantom 'No Entry' episode.

How do I do this  - or can someone please do this for me?
