Powershell function return pscustomobject out-gridview show incorrectly results

This function:

    function Get-UserNameSIDfromAD {        param(            [string] $LoginName        )        [string] $domain        [string] $username        $domain, $username = $LoginName.split('\')        $w32usracc = Get-CimInstance -ClassName win32_useraccount -Filter "Name='$username' and Domain='$domain'" | Select-Object -Property SID        $res = [pscustomobject] @{            ID      = 1            SqlSID  = $w32usracc.SID            Message = 'OK'        }        return $res    }    #Using the function and get the result in variable and show using out-gridview    $val = Get-UserNameSIDfromAD -LoginName 'mydomain\user1'    $val | out-gridview 

Grid shows incorrectly the information, if run the code without function, the grid shows information correctly.

Please any advice, thank in advance.
