I've been using Android Memento for 7 years, and that's just not what happens. Now, keep in mind that the field(s) labeled as entry name is/are displayed within the
edit card, but in the
view card, it is shown at the top, as the name identifies the entry. Some fields can also be labeled as hidden. There is also a provision to suppress the display of the field name in the card. Other than that, it just doesn't happen that way, unless you have found a bug in the app, though in the beta testing Memento, I can attest that the current release does not have such a bug.
