Powershell script to replace characters within multiple files

I have created a Powershell script that will replace a character string with another string, this works file along as only one file is in the directory.

This is the script I am using

#Example of PowerShell replacing text
Clear-host
$Location = "C:\Users\luketr\Desktop\test\*.txt"
$Change = Get-Content $Location
$Change | ForEach-Object {$_ -Replace "'THIRD',", ""} | Set-Content $Location
$Change | ForEach-Object {$_ -Replace "'SECOND',", ""} | Set-Content $Location
$Change | ForEach-Object {$_ -Replace "'FOURTH',", ""} | Set-Content $Location

If I have more than one file in the directory the files are merged.

I have attached the files I am wanting the place the word, SECOND, THIRD and FOURTH in the separate files.

Thanks

Luke
