Duplicate SQL results from Powershell CSV export - sql-server

Question

I am trying to output SQL results to a .csv file using Powershell separated by its respective column.
The script I wrote works, but it will duplicate the same result three times in the csv. Even if I have only 1 result from the Select statement from the table, it will output it three times in the .csv file.
I tried using pscustomobject as well. But it throws me an error and does not output anything.

[string[]] $servers = #('sqlinstance=mytestdb')
foreach($server in $servers)
{
$instance = ($server -split '=')[0]
$db = ($server -split '=')[1]
Try{
$Results = Invoke-Sqlcmd -ServerInstance $instance -Database $db -Query $query
$ExportFolder = ($Results.ItemArray[1])
