Cannot open Declare Pages after upgrade: "Not a rule"



After an upgrade from PRPC 6.2 SP1 to 6.3 SP1 when opening a Declare Pages a message "Not a rule" shows and a page of XML rule data is shown. 

All declare pages including Pega out of the box declare pages do not open.

Clearing the declarative network has not resolved and user cannot create new declare pages.

I suspect the when rule issue is part of the same underlying issue in that something has gone wrong with the upgrade process. I have run the upgrade process again and still have the same issues of being unable to open a Declare Page or When rule.
