POWERSHELL: Commands output differently inside functions [duplicate]

I am learning as I go, this is a small part in a large project but its an inconvenience for me

I am working on a script and one of its functions is to output information about the system.

Now ideally this is the command I would like to use to generate a report of connected drives over 60GB. It lists everything I want.

$size = 60GB

Get-Volume | Where-Object {$_.Size -gt $Size} | Sort-Object {$_.DriveLetter}

I am aware of other commands. They all seem to react the same way to being in a function. So that means I just don't understand what that reason is or how to control that.

If somebody could explain to me why this command outputs differently inside of a function. I've tried Googling however I cannot seem to find anything online. I believe its 100% me not knowing what to Google.

Function ProductConfirmation {
    $processor = (Get-ComputerInfo).CsProcessors.Name
    $product = (Get-WmiObject win32_baseboard).Product
    $gpuname = (Get-WmiObject win32_videocontroller).Name
    $gpudesc = (Get-WmiObject win32_videocontroller).Description
    systeminfo | Select-String  'BIOS Version', 
                                'Network Card(s)', 
                                'OS Name', 
                                'OS Version', 
                                'System Manufacturer', 
                                'System Model', 
                                'System Type', 
                                'Time Zone'

                                                                            'PartNumber', 
                                                                            'ConfiguredClockSpeed'
    ''    
    systeminfo | Select-String  'Total Physical Memory'
    Start-Sleep -s 4
    Write-Host "`n Generating Hard Drive Report`n`n`n"
    Write-Host " Double check all drives that should be with this computer are connected." -ForegroundColor RED
    Start-Sleep -s 4
    $size = 60GB
    Get-Volume | Where-Object {$_.Size -gt $Size} | Sort-Object {$_.DriveLetter}
}
ProductConfirmation

Attached are the outputs of both commands run in a VM.

Top - Run in its function Bottom - Run on its own
