I'm new to Acy6. I'm creation an automation and at the "Actions" step, I choose "choose existing", but then I see the name of this now-chosen newsletter is "name_of_newsletter_copy". And then when I go to choose "Statistics/not sent - "name_of_newsletter" I see 2 copies - the original and now this "_copy" version. Is the Automation/Mass Action system creating a copy of my newsletter every time I select "choose existing"? If so, this will not work - I'm searching for users where my original newsletter has not been sent and if I'm sending this _copy version, then those people will have never been sent the original.
