It might have been nice for you to give this example straight up (although you haven't actually specified the case clearly, I'm still just guessing). So you are creating objects, and 3 of the fields that you have said are unique_together are undefined, and have Null=True in their field definition? In databases, NULL is not equal to anything, even NULL. Eg, NULL == NULL is false. Therefore, 2 rows in the database with the same title, but with NULL for the other 3 fields in the unique index, would not be considered as the same row.
