In season 4 The Twilight Zone became just known as Twilight Zone.  The covers for the Blu-rays all have the The, but on the actual episodes it is not there.

My question is, let's say the Disc is The Twilight Zone: Season 4: Disc One.  Would the Original Title simply be Twilight Zone for every disc, or, in this case, would be Twilight Zone: Season 4: Disc One?

I would lean toward the former but also not sure what it would do to the CLT to enter it that way.
