Custom fields disappeared

Hi,
the box “custom fields” when I edit the property is disappeared.
I am sure that before there was because I used some fields to differentiate the properties.

When I edit pages or posts, the “customs fields” box is present, when I edit properties it’s not present.

Can someone help me?

Sorry for my english 🙂

Thank you
Ale
