New x-custom equivalent?

[RobertZN]

Oops, Just as I pressed the send button, my ISP had some sort of glitch, and went off line momentarily - creating the impression my post had not been sent. I pressed the button again and … voila, two posts. Now I try to remove the extra, and find I can change it, but don't find a way to remove it.

Can an administrator please remove it?
Sorry for the bother
