FileSystemWatcher - Subdirectories

Hello,

I am trying to figure out why FileSystemWatcher will not monitor subdirectories for the parent. I have set IncludeSubdirectories = $true, but it is still only searching the parent.

Folder Structure (D = Directory, F = File)
D --> Resource
D -->> Archive (Resource\Archive)
D -->> MoveIT (Resource\MoveIT)
D -->> Source (Resource\Source)
D -->>> Date (Resouce\Source\Date)
F -->>>> *.csv

Case: If I place the *.csv into Resource\Source directory FileSystemWatcher identifies and takes action. If I place the .csv in Resource\Source\.csv filesystemwatcher does not walk the tree and trigger.

Please keep in mind this is rough code and needs cleaned up, just trying to identify the issue.

Function Wait-Change
{
    
    Param
    (
        [Parameter(Mandatory=$true)]
        [String]$Path,

        [Parameter(Mandatory=$true)]
        [String]$Filter
    )


    $FileWatcher = New-Object System.IO.FileSystemWatcher
    $FileWatcher.Path = $Path
    $FileWatcher.Filter = $Filter
    $FileWatcher.IncludeSubdirectories = $true
    $FileWatcher.EnableRaisingEvents = $true
    $FileWatcher.NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite'

    $OnChange = Register-ObjectEvent $FileWatcher Created -SourceIdentifier FileCreated -Action {
            $name = $Event.SourceEventArgs.Name
            $changeType = $Event.SourceEventArgs.ChangeType 
            $timeStamp = $Event.TimeGenerated
            $Destination = "D:\Resouce\Archive\$name"
            $folder = $Event.SourceEventArgs.FullPath

            Move-Item -Path $folder -Destination $Destination -Force

            Try
            {
                Write-Verbose "Conversion #1"
                #Replace | to ","
                UpdateConfig -path $Destination -source "|" -sourcechanged '","' -file_extension $Filter -RemoteDestination 'D:\Resource\MoveIT' -Verbose 
            }
            Catch
            {
                "Failed Conversion #1"
            }

        }

    While($Global:FileChanged -eq $False)
    {
        Start-Sleep -Milliseconds 100
    }

}

Wait-Change -Path "D:\Resource\Source\" -Filter "*.csv" -Verbose

After further testing, it appears that when a file is created in the sub-directory such as D:\Resource\Source\Date*.csv FileSystemWatcher begins to fail to monitor the parent directory, resulting needing to unregister then re-register the events.
