How to delete a view from the view directory?

So, I’m looking at my screen and I have a sidebar with various views. One of those pulls up the View directory. If I delete one of those views, the sidebar updates to “View # whatever” instead of clearing out, and then that view shows up back in the View Directory as the numeric representation of that View’s position.

Confusing. If I use the “Delete” --> Select View --> Enter function from the keypad, and the view disappears from the view directory, why does it also not disappear from the sidebar?
