ADManager Plus Custom Script Variable only passing first word in multi word attribute

ADManager Plus Custom Script Variable only passing first word in multi word attribute

I'm testing some custom scripts and when it is passing a variable that has more than one word it is only passing the first word. I'm testing this by piping the output to a text file.

Here is what I have in the custom scripts field:
PowerShell -ExecutionPolicy Unrestricted C:\Scripts\Testing-Output.ps1 %givenName% %sn% %extensionAttribute2% %extensionAttribute1% %title% %department% %manager% %l% %telephoneNumber% %extensionAttribute4% %extensionAttribute3% %extensionAttribute5% %company%

Here is the test script: 
param($FN,$LN,$SD,$DOB,$T,$D,$M,$L,$P,$NID,$UIN,$A,$O)
$FN,$LN,$SD,$DOB,$T,$D,$M,$L,$P,$NID,$UIN,$A,$O | Out-File -FilePath C:\Scripts\Output.txt
