Yes I finally discovered that bit of magic myself. What a ridiculously poor User Interface.
I don't see why the dialog didn't have more clear buttons, for example "New", "Edit" and "Delete" would have been more of a standard User Experience than type Create...
And the text states:
"Select Create to Continue" but there is no Create button.
I thought it was a bug and was prepared to wait for an update but finally unlocked the mystery as you did.
