Membership2 kills email verification for new registrations (used with BuddyPress)

I have BuddyPress installed to manage user communication.
I have Membership2 installed to manage user access.
Buddypress is functioning well without Membership activated. However, when I activate Membership2, to use with BuddyPress my new user activation emails do not send. Instead newly registered users can sign in without confirming their email. (Though they're still redirected to the look for an email page after registering).
I'm using the buddy press registration page.
