How do I get rid of unwanted output from a PowerShell script?

I have a function:

function Find-FooBars
{
  [CmdletBinding()]
  [OutputType([array])]
  param
  (
    [string]$appname,
    [string]$eventsId
  )
  $machines = @("server1", "server2")
  $rx = -join ($eventsId, "_.*\.json")
  $answer = [System.Collections.ArrayList]@()
  foreach ($machine in $machines)
  {
    $dir = -join ("\\", $machine, "\c$\Applications\", $appname, "\logs\alerts")
    $arr = Get-ChildItem $dir -Recurse |
      Where-Object { $_.Name -match $rx } |
      Select-Object @{ n = 'LastWriteTime'; e = { $_.LastWriteTime } }, @{ n = 'FullName'; e = { $_.FullName } }
    $answer.Add($arr)
  }
  $answer | Sort-Object -Property LastWriteTime
}

When I invoke the function:

Find-FooBars FooBarMaker 123456

This is the output:

0
1
    
LastWriteTime       FullName
-------------       --------

I would like to get rid of the 0 and 1 at the beginning the output.

[ Edit: There were 2 other questions identified as possible duplicates that talked about indices being inserted into an Array, but I did not see extra values in my ArrayList. My array held just what I expected. But I did see what seemed like spurious extra Console output I wanted gone. ]
