IBM DNG/Report Builder: The Report provides bad result

Morning all,
I installed
IBM CLM 602
SQL SERVER as Database System
iFix014 as Patch

When i created a report in the report builder, i get a false result And i can check in the Rational DNG, and see the false result provide in the report .

Example: I created in the report builder, a report which show the number of artifact linked inside module But I have a false result I have some artifacts linked inside module which don't counted in the report .

I followed the ETL process and refrech the metamodel but the issue is still there. i have a false result.

How do we fix this?
