Release date corrections did not go through and episode deletion request rejected (5/5)

I was trying to fix the episode listings for another Discovery Channel show; most of the edits went through except for two episodes. Additionally, I had sent a request to IMDb's "removal requests" to remove an episode and they told me that it would not be removed. The show only ran for ten episodes so I am very confused as to why there is an eleventh episode listed. Help would be appreciated as always.
