A hidden required field

Hello erveryone,

When I create an IT 6 for the subtype 4 (Emergency adress) for the USA. The screen contains only the telephone number field (nothing else more). But when I try to save this IT, the system tells me that I forgot to key in the STATE field.

Actualy the STATE field is requiered for all USA adresses, but in our case we don't need display all address field just the telephone number field.

Doesn't anyone has an idea to fix that issue ?
