AvailabilityReplica.Role property is always "Unknown"?

Whenever I query AvailabilityReplica.Role property it is always “Unknown” for all the replica servers participating in the AAG except for the one that I’m making the call on.
I do not see this problem when I make the call on primary replica server.

Any idea why it behaves like this and how to get the right information? I do not want to make call to each replica server to get the details.

See the output below.
