When I tried to clone an RM 5.1 App that had a "Cancel Timed Actions This Rule" statement, the cloned rule did not retain the "This Rule" entry in the list as "This Rule"--instead, it referred back to the original rule (the one being cloned).
The cloning process did not offer to allow a substitution for that either. So, the end result was that the cloned rule tried to cancel the ORIGINAL rule's timed actions and not its own.
Is that expected?
