coalesce with count(distinct) can lead to incorrect results

CREATE TABLE test( 

id BIGINT(20) NULL DEFAULT NULL, 

integerfield INT(10) UNSIGNED NULL DEFAULT NULL,

 integerfield2 INT(10) UNSIGNED NULL DEFAULT NULL )

ENGINE=Columnstore;

INSERT INTO test

VALUES (1, NULL,1), (2, NULL,1), (1,NULL,1);

SELECT COUNT(distinct id),        

SUM(integerfield),        

SUM(integerfield2),        

coalesce(SUM(integerfield),0),        

coalesce(SUM(integerfield2),0),        

coalesce(SUM(integerfield),0) + coalesce(SUM(integerfield2),0) 

FROM   test;
