Countdown wait time not working

I’m using the pro version, and trying to get the Wait Time feature to work. The popups appear instantly regardless of the setting of this timer. Am I misunderstanding what this is supposed to do? I would like there to be a delay after loading the page before the popup appears.

I’m using the Avada theme. An example may be seen here (as of 3 Aug, 2017 — this may be deleted in time):

Thanks for any help or insight.
