Powershell script is missing property in result

I am not sure what is wrong with the script. I have a 3 column csv file that consists of Name,Count,Owner. The goal is to get the highest count of each name, then output all 3 columns, however the Owner column is not outputting. I am only getting Name, Total. I would appreciate if someone would assist in showing me what is wrong, many thanks.

$total = Import-Csv -Delimiter ',' -Path "file.csv"

$total = $total | Group-object -Property Name | Select Name,  @{ N = 'Total';E = {($_.Group | Measure-Object -Property count -Maximum).Maximum }},Owner

Contents of csv file:

"Name","Count","Owner"
"ctx_Prd-DG","1","User1"
"PRD-Fa","5","User2"
"ING-PROD","3","User2"
"PROD-DG03","0","User2"
"PROD-DG01","0","User2"
"PRD-2018-DG","1","User3"
"PRD-7-DG","5","User3"
"PRD-7-DG-PR15","0","User3"
"PRD-CS-DG","0","User3"
"PRD-INSIGHT-DG","0","User3"
"PRD-LIVE-DG","0","User3"
"DC01-DG","0","User4"
"Test - DG","0","User4"
"PRD-CS-DG","0","User3"
"INSIGHT-DG","0","User3"
"ctx_Prd-DG","1","User1"
"PRD-Fa","1","User2"
"ING-PROD","0","User2"
"PROD-DG03","0","User2"
"PROD-DG01","0","User2"
"PRD-2018-DG","7","User3"
"PRD-7-DG","5","User3"
"PRD-7-DG-PR15","0","User3"
"PRD-CS-DG","0","User3"
"PRD-INSIGHT-DG","0","User3"
"PRD-LIVE-DG","2","User3"
"DC01-DG","1","User4"
"Test - DG","8","User4"
"PRD-CS-DG","20","User3"
"INSIGHT-DG","0","User3"

Simply $total | Group-Object -Property Name does not have a property "Owner"

# `Get-Member -MemberType Properties` shows properties of an object.
$group = $total | Group-Object -Property Name
$group | Get-Member -MemberType Properties

# See how `Group-Object` groups each item,
$group[1].Group
$group[2].Group

So your code will be like the following

$csv =  Import-Csv "file.csv"
$total = $csv | Group-Object -Property Name | Select Name,  @{
  N = 'Total'
  E = { ($_.Group | Measure-Object -Property count -Maximum).Maximum }
}, @{
  N = 'Owner'
  E = { $_.Group.Owner[0] }
}

Have you considered this option?

$total = Import-Csv -Path file.csv
$grouped = $total | Group-Object -Property Name
$output = $grouped | Select-Object Name, @{ N = 'Total'; E = {$_.Count} }, @{ N='Owner'; E= {($_.Group).Owner}}

Regarding the "Name,Expression" syntax, here is a helpful question posted in SO.

Select-Object expression
