Deleting emails from Nurturing Program

I have cloned a Nurturing Program and want to either replace the email template or create a new email all together and delete the cloned emails. I cannot seem to figure out either. I have deactivated the stream, it will not let me unapprove as it stats the program is in use even though I have deactivated it. I can remove from the stream but not from the email folder.What am I missing, I have confirmed no members are in the program. I cannot figure out how to switch out the template which would make it easier.
