Get-DMSubmittals not showing Responses

We are starting to use the PWPS_PWDM module to extract Deliverables Management submittal information from Bentley Cloud Services.

The Cmdlet Get-DMSubmittals provides some useful information. We are would like to extract Responder Name, Response and Response Comment.

The Get-DMSubmittals Response property is blank:

Folder :
File :
Responses : [Empty]

Any support would be greatly appreciated.
