It could be that you have a missing editpolicies that those actions are
relying upon?

The typical way UI is enabled / disabled is by sending a request to the
current selection (EditParts) and seeing if a command is returned.  If a
command is returned, this indicates that UI can be enabled.  If a null is
returned, then the action is grayed out.  Most often, requests are handled
by the edit policies installed on an EditPart.

Hint:
- See what editpolicies installed in Logic example respond to / handle
requests for the action that you are interested in.

Regards,

Steve.
