DDPM CommandLine Update

Hi all, 

Just working on scripting a firmware update solution and wondering if I am doing anything wrong.

My commandline is 

"C:\Program Files\Dell\Dell Display and Peripheral Manager\Plugins\CLI.Subagent\CLI.Subagent.exe" /set -app=FirmwareUpdate -value=Display,defer

Output is 

{
  "FWVersion": "[M2T101]",
  "FWUpdateRESPONSE": [
    "No updates available: P3424WEB, ServiceTag: XXXXXXX, SerialNumber: XXXXX Version: M2T101"
  ],
  "Model": "P3424WEB",
  "SerialNumber": "XXXXXXX",
  "MarketingName": "",
  "Index": "1",
  "Command": "SET",
  "TargetFeature": "FIRMWAREUPDATE",
  "Value": "DISPLAY",
  "Result": "PASS",
  "Message": "No updates available"
}
However I know there is an update "M2T106".

Is there something I am missing?

Thanks in advance
