I have added a custom document property to my main post office through
Document Properties Maintenance. When I go to import a new document,
when I modify the default values, the new field is not available on the
document sheet. I have tried making it a required field, but no change.

If I do a Find By Example, the new document property is listed there as
an option to find with.

I have forced a reindex on the POA by pressing <ctrl><shift>q on the POA
screen, but no difference.

What can I do to get this field to become available?
