'Redact' button not available while viewing doc in workspace with Document Management System

[AribZ]

I've installed the Document Management System Plugin (com.snc.platform_document_management) in my PDI and uploaded a new document through the Service Operations Workspace. 

When opening the document through the attachment section, a tool bar with many options is avaialble.

In my instance, I'm not able to find the 'Redact' button which is supposed to look like a pencil icon as is found below.

Since I'm using the Instance with the admin role, the issue shouldn't be of accessibility. What could be the reason?

@AribZ 

the pencil icon is shown in which instance? that instance has the same version against your instance for the Document Management System?

If my response helped please mark it correct and close the thread so that it benefits future readers.

Yes, my PDI was running on Washington DC whereas Redaction Feature was released from Xanadu Onwards.
