Two subdomains not seen on dropdown menu

Perhaps I am using the wrong term? There is a drop down menu that lists all the different topics? (is that the correct word) that have been created on this account. All seem to be there except one names Elizabethan and one names Chapter and Verse. I don't know why those topics have disappeared, but is there any way to retrieve them? Thank you!

Oh, I think you're referring to your sites. If there were sites with those names, and they are no longer there, this means they were deleted and there is no way to retrieve them, unfortunately.
