Intermittent 'Confirm Your Email To Get Started'

I have the “member login app” on my site and noticed WIX sometimes asks the user to confirm their email before they can register and sometimes it doesn’t. I want the app to ask every user to confirm their email before registering. Does anybody know why sometimes it asks and sometimes it doesn’t? Is there a setting for this?

I copied a screenshot of when the app asks the user to confirm their email (just to be clear, this is the ‘member login app’ automatically doing it, not me. I did not code a ‘confirm your email’ page). I checked under ‘signup settings’ in my dashboard, but don’t see any mention of this anywhere. Please advise! Thanks!
