PROBLEM WITH COLLATION (NULL) CREATING A DATABASE SQL SERVER

I am creating a database with the following command:

CREATE DATABASE CARGADOR COLLATE SQL_Latin1_General_CP1_CI_AS
GO

When I execute the following command:

select [Collation] = DatabasePropertyEx('CARGADOR','Collation')

The result is:

Collation
NULL

The question is, why NULL ?

The result of the following command:

SELECT SERVERPROPERTY('collation') SQLServerCollation
,DATABASEPROPERTYEX('master', 'Collation') AS MasterDBCollation

SQLServerCollation  MasterDBCollation
Modern_Spanish_CI_AS    Modern_Spanish_CI_AS

Y SELECT @@VERSION
