Execution-Policy Error running Powershell Script in SQL Server Agent

Running a powershell script from SQL Server Agent in 2014 using my AD account via a credential. I am getting the following error.

A job step received an error at line 1 in a PowerShell script. The corresponding line is 'set-executionpolicy RemoteSigned -scope process -Force'. Correct the script and reschedule the job. The error information returned by PowerShell is: 'Security error.

My searches on Google, haven't turned up anything useful. I can run the script from the Powershell console via SSMS at my workstation without any issues.

Execution policy is set at unrestricted

PS C:\WINDOWS\system32> Get-ExecutionPolicy
Unrestricted

The line mentioned in the error output must be getting added automatically by SQL Server because RemoteSigned -scope process -Force is not anywhere in the code.

Is there anything else I need to set in SQL Server Agent, aside from my using AD account to run the job?

Here is the powershell row from msdb.dbo.syssubsystems

C:\Program Files (x86)\Microsoft SQL Server\120\Tools\Binn\SQLPS.exe

This script creates a table serverlist based on the registered servers of a central management server. It then connects to each of those servers and # identifies the port that its listening on.

# connection parameters
 Param ( 
      [string] $CMSServer="someuser\someinstance",  # CMS server that stores serverlist
      [string] $CMSDatabase="msdb",                 # database where the serverlist is stored
      [string] $CMSUser="someuser",         # username to connect to the cms server
      [string] $CMSPassword="somepassword",     # password to connect with the cmsuser
      [string] $CMSTable="dbo.serverlist",          # name of table that stores instances
      [string] $CMSTableNoSchema="serverlist",      # name of table that stores instances
      [string] $UserName="remoteuser",              # username to connect to each instance
