Get a report on AD group membership that showing only unique titles and departments?

Hi, my name is Sasi,

I am need to create an script which can give me a report that goes through certain AD groups and reports out only unique Titles and Departments on those groups.
Experimenting with pscustomobject but whenever I output it just shows the columns with an array of information under neath.

$report = @()
$Distros = Get-ADGroup | ? {$_.Name - like “Critical - *”
foreach ($Distro in $Distros){
$DistroMembers = Get-ADGroupMember -Identity $Distro.SID -Recursive | Where objectclass -eq ‘user’ | Get-ADUser -Properties Displayname,Title,Department | Select DistinguishedName,samAccountName,Name,Displayname,Title,Department
$uTitles = $DistroMembers | select Title -unique
$uDepartments = $DistroMembers | select Department -unique

        $UniqueTitle = $uTitles.Title
        $UniqueDepartments = $uDepartments.Department

        #add line to object
		$obj = New-Object -TypeName PSObject
		$obj | Add-Member -MemberType NoteProperty -Name Group -Value "$Distro.Name"
		$obj | Add-Member -MemberType NoteProperty -Name Title -Value $UniqueTitle 
		$obj | Add-Member -MemberType NoteProperty -Name Department -Value $UniqueDepartments 

		$report += $obj
