GPO Modeling using Powershell

Am using powershell to do GPO Modeling.
$gpmObject = New-Object -ComObject GPMgmt.GPM;
$gpmDomain = $gpmObject.GetDomain('domain.com', 'dc1.domain.com', 0);
$gpmConstants = $gpmObject.GetConstants();
$rsopObject = $gpmObject.GetRSOP($gpmConstants.RSOPmodePlanning,$null,0);
$rsopObject.PlanningDomainController ='dc1.domain.com';
$rsopObject.PlanningComputer ='domain\compName$';
$rsopObject.PlanningUser = 'domain\Administrator';
$rsopObject.planningComputerSOM = 'OU=Domain Controllers,DC=domain,DC=com';
$rsopObject.planningUserSOM = 'CN=Users,DC=lyncforb,DC=local';
$rsopObject.PlanningComputerWMIFilters=@($gpmDomain.GetWmiFilter("MSFT_SomFilter.Domain='domain.com',ID='{11111111-1111-1111-1111-111111111111}'"));
$rsopObject.PlanningFlags=8; //means setting only RSOP_PLANNING_ASSUME_USER_WQLFILTER_TRUE
$createQueryRes=$rsopObject.CreateQueryResults();
$rsopObject.GenerateReport($gpmConstants.ReportHTML).Result;
Here I want only one WMI Filter to be true when simulating GPO Modeling.
But seems $rsopObject.PlanningComputerWMIFilters is not taken into account at all, and all WMI filters associated with GPOs are evaluated as false.
If I set RSOP_PLANNING_ASSUME_COMP_WQLFILTER_TRUE and also use $rsopObject.PlanningComputerWMIFilters, all WMI Filters are considered as true in the result html (again without considering WMI filters specified in $rsopObject.PlanningComputerWMIFilters).
How to make $rsopObject.PlanningComputerWMIFilters relevant and I only want WMI filters specified there only to be evaluated as true.
