I’ve just noticed this also with the “Tab” field – in “input.css” this code is causing the field (in the admin edit screen) to disappear as soon as “Tab” is selected:
.field_type-tab {
display: none !important;
}
You can see it is still there as the field #’s will skip a number where the tab is supposed to be.
Seems like a bug, but correct me if I am wrong or missing something.
