Duplicated results in Powershell - powershell

Question

I have put together a script from various sources, but cannot understand why i am getting duplicated entries in my results..
eg..
I need to check the scheduled tasks on remote servers, and verify which ones didnt complete sucesfully, and then investigate those.
I have a schedulers.csv file, which has two comlumns IP, and Name.
I downloaded the script Get-ScheduledTask.ps1 from https://gallery.technet.microsoft.com/scriptcenter/Get-Scheduled-tasks-from-3a377294
Works great and does what i needed.
I then wanted to from a list retrieve the servers names, run the above script as a parameter, then get back the scheduled tasks in a csv file.
NextRunTime Author Trigger State UserId ComputerName Name LastRunTime LastTaskResult Description NumberOfMissedRuns Enabled Path
The headers for the above script give me Name and LastTaskResult, which is what I wanted to query further.
The LastTaskResult should be 0 if it completed sucesfully, otherwise i would investigate further.
The code i have so far is :
$servers = Import-Csv "C:\test\schedulers.csv"
foreach($server in $servers){
$ServerName = $server.Name
$ServerAddress = $server.IP
Write-Host $ServerName : $ServerAddress
$importfile = Get-ScheduledTask.ps1 -ComputerName $ServerName
|Export-Csv -Path c:\test\scheds.csv -NoTypeInformation
$Lines = Import-Csv "C:\test\scheds.csv"
ForEach($line in $lines){
$lines | %{
$TaskName = $_.name
$taskresult = $_.LastTaskResult
if ($_.LastTaskResult -ne "0")
{
Write-Host $line.LastTaskResult : $_.name : $_.Path
}else{
}
}
}
}
There should be 3 results that show, that have a value of 1 in LastTaskResult, but i get about 38 which is the total amount of tasks on the two servers that i am testing on.
the 3 entries are there also as well, plus all the rest..
please can anyone see where i have gone wrong.. Many Thanks

not tested because i don't have your Get-ScheduledTask.ps1, but here's what i might change
$servers = Import-Csv "C:\test\schedulers.csv"
foreach ($server in $servers) {
$ServerName = $server.Name
$ServerAddress = $server.IP
Write-Host $ServerName : $ServerAddress
$importfile = Get-ScheduledTask.ps1 -ComputerName $ServerName
$importfile | Export-Csv -Path c:\test\scheds.csv -NoTypeInformation
foreach ($line in $importfile) {
if ($line.LastTaskResult -ne '0') {
Write-Host $line.LastTaskResult : $line.Name : $line.Path
}
}
}
